GE Fanuc IC697BEM713 Bus Expansion Receiver Module

The IC697BEM713 is a bus expansion receiver module designed for GE Fanuc Series 90-70 PLC systems. It works cooperatively with the IC697BEM711 bus transmitter module to extend the PLC backplane bus, enabling remote I/O rack expansion over long distances. The module receives high-speed parallel bus signals from the main CPU rack and distributes bus power and communication data to all I/O cards within remote expansion racks. Built-in signal isolation filters eliminate electromagnetic interference from motors and frequency converters to ensure stable long-distance bus transmission.

This legacy expansion communication card has been officially discontinued by GE Automation, serving as critical aftermarket maintenance spare parts for aging Series 90-70 PLC control systems widely used in power, petrochemical and paper industries. It supports hot-swap operation on standard 90-70 chassis, with front-panel LED status indicators to simplify quick fault diagnosis of bus disconnection or power loss during on-site maintenance.

Core Functions

• Receive high-speed bus data signals transmitted from the main PLC rack’s IC697BEM711 module to realize seamless communication between central CPU and remote expansion I/O racks.
• Distribute backplane power and system bus signals to all I/O modules in the remote rack, collecting field input data and forwarding CPU control commands bidirectionally.
• Built-in isolation and noise suppression circuits block ground loop interference and high-frequency radiation from heavy industrial equipment to avoid bus communication dropouts and data errors.
• Hot-swappable single-slot design allows independent module replacement without powering down the entire control system, reducing downtime for continuous production facilities.
• Multi-color front panel LEDs quickly locate bus cable breakage, power supply failure and module hardware faults to improve on-site maintenance efficiency.
• Standard Series 90-70 backplane electrical definition supports plug-and-play replacement, requiring no revision to PLC control programs or rack configuration parameters.
