IC697PWR720 GE Series 90-70 PSA Module for VME Rack Systems

GE Fanuc IC697PWR720: Series 90-70 Power Supply Adapter (PSA)

The IC697PWR720 acts as a precision Power Supply Adapter (PSA) within the GE Fanuc Series 90-70 PLC platform. Engineered to mount directly into the dedicated power supply slot of the baseplate, it converts input energy into clean, regulated DC power for backplane modules. This module is essential for applications requiring VME standard C.1 compatibility and high-capacity backplane energization.

Global PLC Spare HUB's Insight

Our technicians regard the IC697PWR720 as a vital component for extending system life in legacy automation cells. Its unique ability to facilitate dual-rack operations via the IC697CBL700 expansion cable allows engineers to scale I/O without the cost of an additional dedicated power supply. When pairing with third-party supplies, ensure the external unit provides a "Power OK" TTL signal to prevent data corruption during power-down cycles.

Diagnostic Capabilities and Maintenance

• Logic Power LED: Provides instant visual status of the internal voltage regulation.
• Input Signal Monitoring: The module interprets the external "Power OK" signal to ensure orderly system shutdowns.
• Operational Stability: Designed for demanding environments, ensuring consistent VME bus voltage levels.
• Hot-Swap/Maintenance: The single-slot design allows for rapid replacement in established Series 90-70 racks.

Application Environments

• Large-Scale Manufacturing: Reliable power distribution for complex, multi-rack PLC configurations.
• Legacy System Upgrades: Supports VME-standard instrumentation in specialized control loops.
• Distributed Control: Facilitates secondary rack expansion without auxiliary power hardware.

Logistics and Warranty

• Guaranteed 24-48 hour order dispatch.
• Expedited global delivery via FedEx, UPS, and DHL.
• Includes a comprehensive 12-month quality assurance warranty.

Expert FAQ and Selection Guide

Can I use a non-GE external power supply with this PSA?
Yes, you may use a 3rd-party external power supply, provided it meets the 5.05ms minimum hold-up time and provides a valid TTL "Power OK" signal to the IC697PWR720 interface.

How do I implement dual-rack power distribution?
Connect the baseplate to the expansion rack using the IC697CBL700 cable. The PSA will then source power to the secondary rack, provided the total current demand does not exceed module limits.

Why is my module failing to maintain logic power?
First, check the integrity of the external power supply's output. If the external source is stable, inspect the 5V bus load; exceeding the 18A limit will trigger internal protection and inhibit the 'Logic Power' LED.

When is a jumper required on this module?
A jumper is specifically required during installation only when the system logic is configured for negative voltage sensing. Consult your specific backplane schematics before applying this setting.

Selection Guide: Is the IC697PWR720 the right choice for my rack?
Verify your backplane slot configuration. This module is exclusively for the power supply slot in the Series 90-70 chassis. If you are operating a standalone rack with high I/O density, ensure your current calculation accounts for the full 18A capacity of the 5V rail.
