Product Introduction
When upgrading existing control systems from older Series 90-30 platforms to the modern PACSystem RX3i architecture, the GE IC694MDL930 relay output module provides a seamless transition. This module offers eight individually isolated Form A (normally open) relay outputs, each capable of switching both AC and DC loads. Designed for flexible integration, the IC694MDL930 supports nominal voltages of 24 VDC and 120/240 VAC, making it suitable for diverse industrial applications. With a maximum resistive load of 4 Amperes per output, it can drive solenoids, motor starters, and indicator lamps directly.

Compatibility & Integration
The GE IC694MDL930 relay output module integrates into the PACSystem RX3i platform and is also compatible with Series 90-30 backplanes. It functions as a local output module in the CPU rack or as a remote I/O module with appropriate communication adapters. The module supports point-to-point isolation, allowing different voltage levels on each channel. For seamless integration, users can pair it with any RX3i CPU or Series 90-30 controller. This compatibility makes the IC694MDL930 an excellent choice for upgrading legacy systems without replacing the entire I/O infrastructure.
Installation & Setup Guidance
Installing the GE IC694MDL930 module into an RX3i or Series 90-30 baseplate is straightforward. Ensure the backplane power is off before insertion. Align the module with the I/O slot guides and firmly push until the locking tabs engage. The module draws 6 mA from the 5 VDC bus and 70 mA from the 24 VDC relay bus when all outputs are energized. Connect the field wiring to the terminal block according to the channel common and output terminals. Each output is a dry contact; ensure the external power supply matches the load requirements. For UL installations, limit total module current to 20 Amps maximum.
Maintenance & Reliability
The relay contacts in the GE IC694MDL930 are rated for 50,000 to 1,000,000 operations depending on load type and voltage. To maximize contact life, avoid switching loads near the 4 Amp resistive maximum continuously. Regular inspection of output status via the eight channel LED indicators helps identify stuck or failed contacts early. The module's solid-state backplane interface minimizes wear, reducing maintenance frequency. When used within specified voltage and current limits, the IC694MDL930 delivers long service life, lowering total cost of ownership for upgrading control systems.
Selection Guide & Purchasing Advice
Before purchasing the GE IC694MDL930, verify your system's backplane type (RX3i or Series 90-30) and available power supply capacity. This module requires an external power source for the relay coils; ensure your system provides 24 VDC or 120/240 VAC as needed. For high-inrush loads, consider external snubbers or derating.
