PRODUCT INFORMATION
Product Overview
The General Electric IC694BEM331 is a PACSystems RX3i Genius bus controller module. It enables an RX3i rack to exchange data with external devices across a Genius network. Supported platforms include VersaMax systems, Genius blocks, handheld monitors, and distributed field I/O stations. The module operates with a supply voltage of 5 Volts DC and draws 300 mA maximum current.
This communications interface transfers up to 128 bytes of data per message across daisy-chained wiring. It sends and receives up to 128 bytes of global data per bus scan. A single RX3i system supports up to eight Genius bus controller modules. Diagnostics include dedicated status LEDs and isolation rated at 2000 Volts Hi-Pot with 1500 Volts transient common-mode rejection.
