Lubricant level switches for greases
Contactor Based Automatic Transfer Switches
offer an enhanced set of features that will meet your application requirements. They minimize initial equipment costs, reduce installation time, and increase system reliability.
Power Supply Unit series: A1S61PN, A1S62PN, A1S63P
An inverter unit will gradually increase its capacity based on the capacity needed in the room to cool down or heat up the room. The non-inverter can be compared with switching on or off a lamp. Switching on this type of unit will start to run on full load.
Magnetic contactors is a contactor driven by an electric control. Magnetic contactor are a form of electrical relay found on most electrically powered motors. They act as a go-between for direct power sources, and high-load electrical motors in order to homogenize or balance out changes in electrical frequency which may come from a power supply as well as to act as a safeguard. It should be noted that though they are similar in design, magnetic contactors are not circuit breakers. They do not sever the connection between appliance, and power source during a short circuit. They are detachable from a motor so that an operator may work with that motor; disassemble or maintain it, without the possibility of live current still passing through the device.
Applications
Forcing instruction
Basic PLCs are available on a single printed circuit board. They are sometimes called single board PLCs or open frame PLCs. These are totally self contained (with the exception of a power supply) and, when installed in a system, they are simply mounted inside a controls cabinet on threaded standoffs. Screw terminals on the printed circuit board allow for the connection of the input, output, and power supply wires. These units are generally not expandable, meaning that extra inputs, outputs, and memory cannot be added to the basic unit. However, some of the more sophisticated models can be linked by cable to expansion boards that can provide extra I/O. Therefore, with few exceptions, when using this type of PLC, the system designer must take care to specify a unit that has enough inputs, outputs, and programming capability to handle both the present need of the system and any future modifications that may be required. Single board PLCs are very inexpensive (some less than $100), easy to program, small, and consume little power, but, generally speaking, they do not have a large number of inputs and outputs, and have a somewhat limited instruction set. They are best suited to small, relatively simple control applications.
are generally capable of handling 8 or 16 and, in some cases 32, on-off type inputs or outputs per module. Modules are specified as input or output but generally not both although some manufacturers now offer modules that can be configured with both input and output points in the same unit. The module can be specified as AC only, DC only or AC/DC along with the voltage values for which it is designed.
gnal from a tachometer or other frequency generating device. These modules can also count the incoming pulses if desired. Generally, both frequency and count are available from the same module at the same time if both are required in the application. Register input and output modules transfer 8 or 16 bit words of information to and from the PLC. These words are generally numbers (BCD or Binary) which are generated from thumbwheel switches or encoder systems for input or data to be output to a display device by the PLC.
device (LED or LCD) for viewing program steps or functions More advanced systems employ a separate personal computer which allows the programmer to write, view, edit and download the program to the PLC.
Specification: Programmable Logic Controllers (PLC)
Programmable Logic Controllers (PLC) were first created to serve the automobile industry, and the first programmable logic controller project was developed in 1968 for General Motors to replace hard-wired relay systems with an electronic controller.
Programmable Logic Controllers, are frequently used to synchronize the flow of inputs from sensors (Physical) and events with the flow of outputs to actuators and events. This leads to precisely controlled actions that permit a tight control of almost any industrial process.
This is actually a control device that consists of a programmable microprocessor, and is programmed using a specialized computer language. 
Before, a programmable logic controller would have been programmed in ladder logic, which is similar to a schematic of relay logic. A modern programmabl logic controller is usually programmed in any one of several languages, ranging from ladder logic to Basic or C. Typically, the program is written in a development environment on a personal computer (PC), and then is downloaded onto the programmable logic controller directly through a cable connection. The program is stored in the programmable logic controller in non-volatile memory.
Programmable logic controllers contain a variable number of Input/Output (I/O) ports, and are typically Reduced Instruction Set Computer (RISC) based. They are designed for real-time use, and often must withstand harsh environments on the shop floor. The programmable logic controller circuitry monitors the status of multiple sensor inputs, which control output actuators, which may be things like motor starters, solenoids, lights and displays, or valves.
Digital signals yield an on or off signal, which the programmable logic controller sees as Boolean values. Analog signals may also be used, from devices such as volume controls, and these analog signals are seen by the programmable logic controller as floating point values.
There are several different types of interfaces that are used when people need to interact with the programmable logic controller to configure it or work with it. This may take the form of simple lights or switches or text displays, or for more complex systems, a computer of Web interface on a computer running a Supervisory Control and Data Acquisition (SCADA) system.
Distributed Control System (DCS)
Distributed Control System (DCS) is a system of dividing plant or process control 
into several areas of responsibility, each managed by its own controller, with the whole system connected to form a single entity, usually by means of communication buses.
Distributed Control System (DCS) refers to a control system usually of a manufacturing system, process or any kind of dynamic system, in which the controller elements are not central in location (like the brain) but are distributed throughout the system with each component sub-system controlled by one or more controllers. The entire system of controllers is connected by networks for communication and monitoring.
A DCS typically uses custom designed processors as controllers and uses both proprietary interconnections and Communications protocol for communication. Input & output modules form component parts of the DCS. The processor receives information from input modules and sends information to output modules. The input modules receive information from input instruments in the process (a.k.a. field) and transmit instructions to the output instruments in the field. Computer buses or electrical buses connect the processor and modules through multiplexer or demultiplexers. Buses also connect the distributed controllers with the central controller and finally to the Human-Machine Interface (HMI) or control consoles
What is the difference between PLC and DCS?
The main difference between Programmable Logic Controller (PLC) and Distributed Control System (DCS) are:
The number of I/O in the system. DCS is dealing with very large no. of I/O with less cost. also DCS comes with it's SCADA always. if DCS stopped, all system is stopped. if the system has less No. of I/O, then PLC is better from cost view. Also SCADA is optional. if system is controlled by no of PLC. if PLC is down. others continue working Normally. Historical, main difference was that DCS deal with Analogue signals but PLC deal with Discrete digital system. Now DCS has Digital Modules and PLC has Analogue modules.
Besides, PLC has a processor and input and output cards (I/O card could be digital and/ or analog) Processor has the software - basis the input it receives from field devices it gives out the output commands to control devices of the field. DCS is a group of individual smart controllers (again having embedded software and connections with field devices) doing their specified operation (duty) but interconnected.
What is Industrial Automation?
Automation is the use of control systems (such as numerical control, programmable logic control, and other industrial control systems), in concert with other applications of information technology (such as computer-aided technologies [CAD,
In the scope of industrialization, automation is a step beyond mechanization by use of robotic 
devices to complete manufacturing tasks. Whereas mechanization provided human operators with machinery to assist them with the physical requirements of work, automation greatly reduces the need for human sensory and mental requirements as well. Processes and systems can also be automated.
In this day and age of computers, industrial automation is becoming increasingly important in the manufacturing process because computerized or robotic machines are capable of handling repetitive tasks quickly and efficiently. Machines used in industrial automation are also capable of completing mundane tasks that are not desirable to workers. In addition, the company can save money because it does not need to pay for expensive benefits for this specialized machinery. There are both pros and cons for a company when it comes to industrial automation.
On the plus side, with soaring healthcare costs, paid days off, vacation time, and other costly employee benefits, companies can save money with industrial automation. While robotic machinery can initially be extremely expensive, the loss of monthly wages for production workers leads to incredible savings for the company. While machinery used for industrial automation can break down, it does not happen often. If it does, only a handful of maintenance or computer engineers are needed to handle repairs and get lines running smoothly again.
In addition, many plants hire dozens of production workers for a variety of shifts and need to close on certain days. Industrial automation, however, allows a company to run the plant twenty-four hours a day, 365 days a year, without paying overtime. This fact alone can add up to significant savings.
A company that employs forty-eight factory workers on three different shifts and closes on weekends, for example, can save thousands of dollars with industrial automation. This is particularly true if weekend work is necessary, which means overtime pay of time and a half must be paid for Saturday work and double-time for Sunday. This equates to an additional twelve hours of pay per employee. Of course, life insurance, 401K benefits, dental insurance, health insurance, pension coverage, and disability also contribute to the expense.
Industrial automation can eliminate the need for all forty-eight jobs. The robotic machinery used for industrial automation may only involve a monthly payment until the machinery is paid for, a couple technicians to keep the robotic machinery running, and electricity costs. Unfortunately for workers, industrial automation can eliminate thousands of jobs. As the workforce decreases and the cost of living increases, many families struggle to make ends meet as their jobs are replaced by high-tech machines.
Advantages and disadvantages
The main advantage of automation are:
The main disadvantages of automation are:
Input - Output I/O 
faults and also to stop electrical ‘noise’ corrupting the processor’s operations. Interference can be more of a problem on outputs because higher currents are being controlled by Computers and industrial
The external devices (solenoids, motor starters, limit switches, etc.) operate at voltages up to 110 V AC. The mixing of these two voltages will cause severe and possibly irreparable damage to the PLC electronics. Less obvious problems can occur from electrical ‘noise’ introduced into the PLC from voltage spikes on signal lines, or from load currents flowing in AC neutral or DC return lines. Differences in earth potential between the PLC cubicle and outside plant can also cause problems.Simple to use and cost saving, the Micro-Controller PXR is available in 4 sizes: 24x48 (PXR3), 48x48 (PXR4), 48x96 (PXR5) and 96x96 mm (PXR9).
