Product Introduction
When controlling industrial actuators, solenoids, and motor starters, the GE IC694MDL940 relay output module delivers reliable switching with a fast 15 ms response time. Part of the PACSystem RX3i series, this module features 16 normally open (N.O.) contacts grouped into four groups of four outputs each. It supports both DC (5-30 VDC) and AC (5-250 VAC at 47-63 Hz) loads, making it ideal for mixed-voltage environments.

Industry Applications
The GE IC694MDL940 excels in applications requiring reliable on/off control of high-current devices. Typical uses include controlling motor starters in conveyor systems, energizing solenoid valves in process lines, and driving indicator lamps in control panels. Its 2 Amp per output capacity and 4 Amp per common design ensure robust performance. The long relay contact life (up to one million operations) translates to lower replacement costs and reduced downtime, offering a strong return on investment over the product's lifecycle.
Maintenance & Reliability
To maximize the lifespan of the GE IC694MDL940, perform periodic inspections of relay contact wear. The module does not include an internal fuse; install external fuses on each output group to protect against overcurrent. The LED front panel provides real-time status for each channel, simplifying troubleshooting. Operate within the specified voltage range (5-30 VDC or 5-250 VAC) to prevent premature contact degradation. With proper external protection, the module's relay contacts can achieve hundreds of thousands of operations under typical pilot duty conditions.
Selection Guide & Purchasing Advice
Before purchasing the GE IC694MDL940, verify compatibility with your PACSystem RX3i backplane. The module occupies a single slot and requires 5 VDC and 24 VDC power from the backplane. For external field devices, use an appropriate AC/DC power source (sold separately). UBEST Automation stocks this module and ensures genuine OEM parts.
