IC687RCM711
GE
Overview
The IC687RCM711 is a Redundancy communications module from GE. It extends the GE product portfolio connectivity through its onboard communication interface.
Application & Technical Notes
As a redundancy communications module, the IC687RCM711 is intended for deployment in panel-based control cabinets and machine enclosures where the GE product portfolio equipment is installed. It bridges the controller to higher-level networks, HMIs, SCADA and peer devices, carrying configuration, process data and diagnostics.
Specific electrical and mechanical ratings depend on the exact configuration and suffix of the part; the original datasheet should be consulted for the definitive specification.
Maintenance & Diagnostics
Confirm network addressing, baud/rate and topology match the rest of the system; keep firmware consistent across the cell. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.
Sourcing & Procurement
When sourcing the IC687RCM711, distinguish three supply tiers: (1) genuine GE stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.
Match the protocol, connector and topology to the rest of the GE product portfolio network and to the peer devices already installed. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

Specifications (source data)
The GE Fanuc Automation IC687RCM711 redundancy communications module is applied to a hot standby CPU redundancy system. It requires a current of 1.2 Amps and it comes with 5 LED indicators and a pushbutton. Technical specifications for IC687RCM711 Brand GE Fanuc Series Series 90-70 Part Number IC687RCM711 Type Redundancy communications module Current required 1.2 Amps (From 5V Bus) Maximum cable length 15 m Effective data rate 500 KB/sec Electrical isolation Non-isolated differential communication VME Designed to support VME standard C.1 LED indicators Yes, 5 Pushbutton Yes Connectors Two, top and bottom Systems Hot Standby and Enhanced Hot Standby CPU Redundancy system The IC687RCM711 communications module is designed and distributed by GE Fanuc Automation. This part is used in a system known as a “Hot Redundancy System”. The purpose of the part is to synchronize the CPUs that are installed in this system. It uses existent data in the back-up unit to perform this specific operation. The module can also be used to transfer data from one CPU to another when connected to this system. The GE Fanuc Automation IC687RCM711 communications module can be wired with at least 7.5 meters of cable. It is compatible with the GE IC697 series CPUs from the same series. When it comes to installation space, this module only requires a single slot and it includes 2 different connectors. The most common slot is the one that is placed on the top cover of the module.
The GE Fanuc Automation IC687RCM711 communications module performs data transfers with a speed of up to 500 KB per second. Unlike other similar devices, this communications module does not require any kind of isolation. This module also includes 5 LED indicators that are green to show the current status of the application process and the CPUs. For a human-machine interface, the GE Fanuc Automation IC687RCM711 communications module has a physical pushbutton. The function of this button is to change the control from the unit to the back-up unit when required. It is necessary that both units be ready to use, and once they have been switched, it is necessary to wait 10 seconds to switch them back again. This module has a current rating of 1.2 Amps.
