GE Fanuc IC694MDL940 Voltage Output Module

The IC694MDL940 acts as a high-capacity discrete interface for the Emerson PACSystems RX3i controller family. This module provides sixteen independent relay outputs to manage heavy industrial loads. It effectively controls external hardware such as solenoid valves, indicators, and motor starters. Because it utilizes mechanical contacts, the module supports both AC and DC voltage applications. The hardware installs into any standard I/O slot within the RX3i universal backplane.

Isolation and Protection Characteristics

Robust galvanic isolation protects the PLC backplane from field-side electrical interference. This unit provides 1500 VAC isolation for one minute between field wiring and the logic bus. Furthermore, it maintains 250 VAC continuous isolation between separate output groups. Since this module lacks internal fuses, users must install external protection. Proper external fusing prevents permanent relay damage during short-circuit events or overloads.

Diagnostic Interface and Connectivity

The front panel features sixteen status LEDs for real-time monitoring. These indicators confirm the logic state of every individual output channel. Consequently, maintenance personnel can verify module operation without specialized tools. The unit requires a removable terminal block for field wiring connections. This design facilitates quick module swapping during system maintenance or upgrades.
