GE IC694MDL930 – 8-Channel Relay Output Module Overview
Product Overview
The GE IC694MDL930 is a relay output module from the PACSystem RX3i platform, now under Emerson Automation. This module offers eight individually isolated Normally Open (N.O.) Form A contacts. Each output handles 5-30 VDC or 5-250 VAC loads with a maximum current of 4 Amps per point (resistive) and 2 Amps for pilot duty. The module is ideal for switching indicators, motor starters, and solenoids in industrial settings.

Design and Installation
The IC694MDL930 mounts directly into an RX3i or Series 90-30 backplane. It functions as a local output module in the CPU rack or as part of an expansion or remote I/O station via a communication adapter. Each channel has a separate common terminal, allowing different voltage types and levels per point. The module does not include fuses or RC snubbers, so external protection may be required for inductive loads.
Performance and Reliability
With a relay contact life ranging from 50,000 to 1,000,000 operations (depending on load), the IC694MDL930 offers reliable switching. The 15ms response time suits most discrete control applications. The module supports minimum loads of 10 mA, ensuring proper contact wetting. Its inrush rating of 5 Amps prevents nuisance trips during startup.
Applications
Common uses include switching AC or DC motors, valves, solenoids, and indicator lights. The isolated outputs allow mixing voltage types on the same module. Engineers can use this module in packaging, material handling, and process control systems where robust relay outputs are needed.
Conclusion
The GE IC694MDL930 provides a flexible, high-current relay output solution for the PACSystem RX3i. Its eight isolated Form A contacts, wide voltage range, and easy integration make it a reliable choice for industrial automation professionals.
