GE IC200ERM002C – Expansion Receiver for VersaMax Remote I/O

This expansion receiver connects a remote I/O station to the main CPU backplane. It links the VersaMax controller with distributed field devices over long distances. You will need this module when placing I/O racks away from the main cabinet.

Key Technical Specifications

Physical Layout and DIN Rail Mounting

This module measures 130 mm in width and 110 mm in height. Its depth reaches 55 mm for standard VersaMax enclosures. The unit weighs 310 grams, allowing easy installation on crowded DIN rails. Four locking clips secure the module without additional mounting hardware.

Internal Circuitry and Energy Storage

One hundred eight components populate this communications adapter board. A 3300 µF capacitor bank filters incoming DC power for clean operation. This energy storage also bridges brief supply interruptions up to 10 milliseconds. Consequently, the receiver maintains link status during momentary voltage dips. The onboard transceiver converts RS-485 signals to backplane logic levels.

Communication Protocol and Distance Limits

The module uses a 2-wire RS-485 serial link at 115.2 kbps. You can run standard shielded twisted-pair cable up to 200 meters. This distance lets you place I/O stations near machinery while keeping the CPU safe. The receiver automatically detects and retransmits messages to all local modules. Therefore, you can expand a single controller across a large factory floor.

Status Indication and Field Wiring

Four front-panel LEDs show power, health, transmit, and receive activity. A green PWR light confirms proper 24V DC supply connection. The OK LED flashes during normal communication and stays solid during errors. You connect the RS-485 cable to a removable 3-position terminal block. This block accepts wires from 0.2 mm² to 1.5 mm² cross-section.
