GE IC693PWR330H Power Supply Module

The GE Fanuc IC693PWR330H, also cataloged as the IC693PWR330 Power Supply Module, operates as a dedicated hardware component for system power conversion and backplane rail regulation within Series 90-30 PLC platforms.

Hardware Specifications

Backplane Bus Power Architecture & Protocol Execution

The module is built with an integrated power conversion stage designed to maintain backplane bus communication velocity and stable rail regulation across expanded rack topologies. It delivers up to 7 A on the +5 VDC rail to ensure backplane logic integrity, while providing dedicated deterministic power feed paths for local CPU and expansion I/O operations. Internal circuitry features electronic overcurrent limits and hardware jumper selection between terminals 3 and 4 for overvoltage loop suppression, maintaining signal purity and reducing noise coupling into high-density rack modules.

Frequently Asked Questions

Q: What specific slot location is required for mounting this power supply module on the baseplate?

A: The module must always be installed in the leftmost slot (slot 0) of the Series 90-30 baseplate to properly interface with the backplane power bus.

Q: How is overvoltage protection configured on the field wiring terminal block?

A: Overvoltage protection functionality is activated or bypassed via a hardware jumper connection placed across terminals 3 and 4 of the front 6-terminal block.

Field Installation Guidelines

1. De-energize the main line voltage source before attempting to mount or wire the power supply module.
2. Slide the module into the designated leftmost slot of the baseplate until the rear backplane connectors and locking mechanisms fully engage.
3. Wire the incoming AC or DC supply lines to the 6-terminal block, ensuring protective conductor (earth ground) is properly bonded to terminal 1.
4. Maintain proper field wiring isolation by routing input AC/DC power cables separately from low-voltage signal wires and RS-485 serial communication cabling.
