Structure and Composition

Unlike larger modular PLC systems, the GE CP238TA is designed as a compact all-in-one unit, integrating CPU, I/O interfaces, and communication ports into a single housing. The chassis is constructed from high-durability, flame-retardant polymer, suitable for demanding factory environments.

• Front Panel: Houses status LEDs for power, communication, and I/O activity.

• Terminal Blocks: Clearly labeled for easy connection of input/output devices.

• Communication Ports: Support multiple industrial protocols for data exchange.

• Internal Architecture: Built around a high-speed microcontroller with dedicated memory for program execution and data storage.

This integration reduces wiring complexity, saves space, and simplifies installation.
