I/O modules are building blocks of industrial control systems used in end equipment such as PLC (Programmable Logic Controllers), PAC (Programmable Automation Controller) and DCS (Distributed Control ...

Analog devices use continuous signals that vary in magnitude, such as voltage, current ... special analog modules and conversion circuits must be used to interface with the PLC.

Some specific real-world examples of discrete inputs to a PLC would be open or closed circuit breakers ... Basically the analog input module either measures voltage or current from the input device.

Use configurable current limiting ... utilizing a digital-input translator/serializer and a data isolator. The Corona design provides the front-end interface circuit of a PLC digital input module. The ...
