IC694MDL231 | GE PACSystems RX3i 8-Channel Isolated Input

GE Fanuc IC694MDL231 PACSystems RX3i 240VAC Isolated Input Module

The IC694MDL231 (Model: IC694MDL231) is a high-voltage discrete input module engineered for the GE Fanuc (Emerson) PACSystems RX3i platform. Specifically designed for high-interference industrial environments, this module provides 8 isolated input points that interface directly with 240 VAC field devices. Unlike standard common-return modules, the IC694MDL231 features individual channel isolation, allowing each input to be wired to different phases or separate power sources. This architectural choice ensures maximum noise immunity and prevents electrical faults from propagating across the PLC backplane, making it an essential component for heavy industrial power distribution and utility control.
