Product Introduction
GE Fanuc IC698PSA350 Product Introduction
GE Fanuc IC698PSA350 is a high-capacity power supply module for PACSystems RX7i PLC racks. It converts incoming AC or DC power into regulated backplane voltages required by RX7i CPU, communication, and I/O modules. The module also provides rack sequencing signals and diagnostic status monitoring.
The main reason plants keep GE Fanuc IC698PSA350 in service is its ability to support large RX7i configurations with high module counts. Before replacement, engineers should confirm total rack power demand, airflow availability, and hardware revision because the 350W rating depends on proper cooling conditions.

Application Scenarios & Field Pitfalls (The Engineer’s Perspective)
Engineering Pain Point
A production line stops after a controller rack loses power unexpectedly. The CPU may appear damaged, but the actual failure is often upstream in the power supply layer. Aging capacitors, blocked airflow, or overloaded rack power demand can cause intermittent faults that are difficult to reproduce.
The power supply is the foundation of the PLC rack. A stable CPU cannot compensate for unstable backplane power.
Typical Applications
- Automotive Manufacturing – RX7i PLC racks controlling assembly lines, robotic cells, and material handling systems.
- Power Generation – Control panels for auxiliary systems, turbine balance equipment, and plant automation packages.
- Water Treatment – Pump control systems, filtration processes, and distributed PLC control cabinets.
- Heavy Industry – Large machine control systems requiring multiple communication and I/O modules in one RX7i rack.
Technical Pitfalls to Avoid
- Check Rack Power Consumption Before Replacement
The IC698PSA350 provides higher output capability than standard RX7i supplies. Confirm actual module load before installation. An overloaded rack can create repeated power alarms. - Do Not Ignore Cooling Requirements
Full 350W operation requires proper forced-air cooling. A failed fan tray or restricted airflow can trigger overtemperature protection. - Verify Input Voltage Configuration
The module accepts wide AC and DC input ranges, but field wiring must still match the plant power design. Confirm terminal wiring and grounding before energizing.
