GE Fanuc | IC698PSA100D Power Supply

The GE IC698PSA100D is a high-performance power supply module designed for the GE Fanuc PACSystems RX7i programmable automation controller series. This module provides the necessary power to the VME backplane of the RX7i rack, ensuring stable operation of the CPU, I/O modules, and communication cards in demanding industrial applications.

Technical Specifications

Application Areas

• PACSystems RX7i Architecture: Used as the primary power source for large-scale control systems.
• Redundant Power Configurations: The RX7i rack supports dual-power supply configurations, where two PSA100 units can be installed for seamless failover protection.
• Process Automation: Critical for industrial automation and power control where downtime must be minimized.
• Complex Logic Processing: Supports racks populated with high-density analog/digital I/O modules and high-speed communication interfaces.

Product Usage Guide

1. Safety: Always verify that the input power source matches the voltage range (AC or DC) before connecting to the terminal block.
2. Installation: Slide the power supply into the designated slot on the left side of the RX7i rack. Ensure the front-panel captive screws are tightened to maintain a proper chassis ground.
3. Redundancy: If using a redundant pair, ensure both modules are connected to independent power circuits to prevent a single power failure from causing a total system shutdown.
4. Monitoring: The front panel features LEDs (Power OK, Fault, etc.). If the “Fault” LED is active, check for a short circuit on the backplane or an internal module failure.

Frequently Asked Questions (Q&A)

Q: Can the IC698PSA100D be used in RX3i systems?

A: No. The PSA100 is specifically designed for the RX7i (VME-based) rack. The RX3i system utilizes a different power supply form factor (IC695 series).

Q: What does the “D” suffix represent?

A: The “D” at the end of the part number indicates the hardware revision level. Higher letters generally represent updated circuitry or improved thermal management.

Q: How do I know if my power supply is failing?

A: Common symptoms include intermittent system restarts, “Loss of Power” errors in the controller’s diagnostic buffer, or the “Fault” LED illuminating on the front panel.
