GE IC694MDL940

Product Overview

The IC694MDL940 is a 16‑channel normally‑open (Form A) relay output module from GE Fanuc (Emerson Automation) for PACSystems RX3i PLCs, offering 16 individually isolated outputs split into 4 groups of 4, each with a dedicated common terminal. It switches AC/DC loads (5–250VAC, 5–30VDC) with 2A per point (pilot duty), 4A per group common, and 5A inrush handling, plus 250VAC continuous (1500VAC surge) field‑to‑backplane/point‑to‑point isolation. It has 15ms on/off response, per‑channel LED indicators, and runs on +24VDC backplane power (135mA) with no external supply needed. The single‑slot module converts PLC digital commands into relay‑switched signals for industrial actuators, ideal for mixed AC/DC control with noise immunity and safety isolation.
