PLC and I/O Modules

Programmable Logic Controllers (PLCs) are computers designed to automate electromechanical processes. They are used in a wide range of applications including assembly lines, food processing, transportation, injection molding and water treatment. PLCs are typically designed for harsh environments and include multiple input/output (I/O) ports to monitor process variables and actuate external systems. These I/O ports may be built in the PLC or they may be housed externally in separate I/O modules.
