GE IC694BEM331 Genius Bus Interface Module
Product Overview
The GE IC694BEM331 is a Genius Bus Interface Module designed for GE’s RX3i PACSystems, a key platform in industrial automation. This module enables communication between the RX3i PLC and other devices on a Genius bus network, such as I/O modules, HMIs, and other PLCs. It acts as a bridge, ensuring data flows smoothly between components to coordinate tasks in industrial systems.
As part of the IC694 Series, the GE IC694BEM331 fits into any I/O slot of RX3i backplanes like the IC694CHS790. It connects to the backplane to exchange data with the PLC’s CPU, such as the IC694CPU331. The IC694BEM331 supports the Genius bus protocol, a reliable industrial standard, with a data transfer rate of 153.6 kbps. This speed ensures real-time communication, critical for fast-paced processes like assembly lines or packaging systems.
Built to handle tough industrial conditions, the GE IC694BEM331 operates in temperatures from 0°C to 60°C and humidity up to 95% (non-condensing). It resists dust and vibrations, working reliably in factories, power plants, and water treatment facilities. Even though it is a legacy model, the GE IC694BEM331 remains vital for maintaining older systems, allowing businesses to avoid full upgrades while keeping their automation infrastructure functional.

Main features and advantages
Genius bus compatibility: The IC694BEM331 supports the Genius bus protocol, a widely used standard in industrial networks. This allows the RX3i PLC to connect to a wide range of Genius devices, from I/O modules to HMIs, without needing special adapters.
Fast data transfer: With a rate of 153.6 kbps, the module ensures data moves quickly between the PLC and network devices. This speed is crucial for real-time applications, such as adjusting a conveyor’s speed when a sensor detects a product jam.
Large device capacity: The IC694BEM331 can connect up to 32 Genius bus devices. This makes it suitable for large systems, like a car factory with multiple assembly stations, each with its own sensors and actuators.
Tough industrial design: The module works in temperatures from 0°C to 60°C and resists humidity and dust. This durability ensures reliable operation in harsh environments, such as food processing plants or outdoor installations.
Easy integration: The IC694BEM331 fits into any I/O slot of RX3i backplanes. It connects to the network via simple wiring, using cables like the IC694CBL324. This makes it easy to add to existing systems or replace old modules.
Legacy system support: Many older industrial setups still use Genius bus networks. The IC694BEM331 lets these systems keep running without expensive upgrades. It works with existing cables and devices, saving time and money.

Installation and maintenance
Pre-installation preparations: Check that the IC694BEM331 is compatible with your RX3i backplane (like the IC694CHS790) and CPU (like the IC694CPU331). Ensure there is an empty I/O slot. Power off the system and disconnect all power sources. Align the module with the slot and push firmly until it clicks into place. Connect the Genius bus cable to the module’s port, using a cable like the IC694CBL324. Tighten the cable’s screws to secure it. Power on the system and check the module’s green status light—this means it is working.
Maintenance suggestions: Inspect the IC694BEM331 every month. Wipe dust off with a dry cloth to prevent overheating. Check the network cable connections to make sure they are tight—loose cables can cause data delays. If the status light turns red, power off the system, remove the module, and reinsert it to fix loose connections. Keep a spare IC694BEM331 in a dry, cool area (10–30°C) to replace quickly if needed, minimizing downtime.
