Product Overview

The IC694MDL240 serves as a 120 VAC discrete input module for the GE Fanuc / Emerson PACSystems RX3i platform. This 100% brand new, original module provides 16 input points for monitoring AC-powered field devices such as limit switches, selector switches, and motor starter auxiliary contacts. It converts AC field signals into logic-level data for the RX3i CPU, ensuring reliable signal acquisition in industrial environments.

Technical Specifications

Engineering Advantages

Optimized AC Sensing
Built-in filtering and debounce characteristics (30 ms ON / 45 ms OFF) reduce noise from AC line fluctuations and mechanical contact chatter, improving signal stability.

Simplified Wiring Architecture
A single 16-point group design reduces wiring complexity, minimizing neutral return paths and improving panel layout efficiency.

Universal Backplane Integration
Compatible with RX3i Universal Backplane and legacy expansion racks, enabling flexible system integration across mixed architectures.

Reactive Power Efficiency
Low 5 VDC backplane consumption (90 mA) minimizes load on system power supplies, allowing higher I/O density per rack.

FAQs

Can this module be used with 240 VAC signals?
No. It is rated up to 132 VAC maximum. Using 240 VAC will damage the module. For 240 VAC applications, use a dedicated 240 V-rated module such as IC694MDL241.

How do I identify input status?
Each of the 16 channels has an LED indicator. When lit, the input is receiving an ON-state AC voltage (74–132 VAC).

Does the module include a terminal block?
Yes. A removable 20-screw terminal block is included for pre-wiring and fast replacement.

Is there a DC equivalent?
Yes. For 24 VDC applications, DC input modules such as IC694MDL645 are used instead of AC input variants.
