Explanation of Solution

Discussion:

A solid-state, electronic microprocessor-based control system is known as a programmable controller.

A programmable controller contains the following components.

  • Power supply.
  • Input modules.
  • Processor.
  • Output modules.
  • Programmer.

The input devices such as push buttons, limit switches, and condition sensors are connected to input modules. The input module is monitored by the system to detect changes occurred in the input devices. Depending upon the status of input signals, the controller system reacts using user- programmed internal logic. The response obtained by the controller device is used to drive the output loads such as motor starter, control relays, contactors, and alarms.

The major control devices of a programmable controller are shown in Figure 1.
