GE Fanuc IC694BEM331 Genius Bus Controller Module

Overview

The IC694BEM331 is a Genius Bus Controller module designed for use with GE Fanuc's RX3i PACSystems. It enables communication between the RX3i system and other devices on the Genius Bus, such as VersaMax, Genius Block, Genius Hand-Held Monitors (HHM), and remote or distributed I/O systems. The module supports a high-speed data exchange, allowing up to 128 bytes of data to be transferred between the RX3i system and connected Genius-capable devices.
