The IC694MDL754 is a high-density discrete output module for the PACSystem RX3i platform. This unit provides thirty-two independent output channels to control external devices like valves and relays. It operates on a 12/24 VDC nominal voltage with robust protective features for reliable automation.
Hardware Configuration and Electrical Design
This GE RX3i module organizes its thirty-two channels into two fully isolated groups of sixteen. Each channel actively sources current with a positive logic configuration for straightforward wiring. The design includes comprehensive safeguards against short-circuits, overcurrent, and overtemperature conditions. Furthermore, these protections feature auto-recovery to maintain system uptime after a fault clears.
