GE Fanuc IC698PSD300 | PACSystems RX7i Power Supply Module

Product Overview

The GE Fanuc IC698PSD300 serves as the primary IC698PSD300 Power Supply Module utilized to execute direct-current electrical distribution across PACSystems RX7i backplane platforms. It converts a nominal 24 VDC external input source into regulated internal output voltages required by the rack-mounted processing units, memory expansions, and network communication sub-assemblies. The module incorporates an internal diagnostic network that reports power rail integrity metrics continuously via a specialized backplane monitor.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks Alignment and Backplane Management

The module utilizes an explicit physical interface topology designed to support modern network demands, matching the stringent execution timelines of Profinet / EtherNet/IP deterministic networks. The internal logic provides precise sequencing of the distinct 5.1 VDC, 3.3 VDC, and dual 12 VDC output rails during standard power-up and power-down cycles. High thermal dissipation efficiency limits ambient internal casing stress under maximum electrical loads, maintaining consistent firmware flash compatibility across connected backplane processors.

Frequently Asked Questions

Q: Does this power supply support load sharing configuration for N+1 redundancy?

A: No. The internal diode isolation pathways within this model are configured for standalone operation. Paralleling two identical units on a single standard rack to increase output current rating or establish dynamic backup loops is not supported.

Q: What is the behavior of the internal safety circuits during an output short-circuit event?

A: The module executes an automatic electronic shutdown policy if an overcurrent or short-circuit condition manifests on any output rail. The system will enter a continuous retry latch cycle until the field electrical fault is removed and input power is cycled.

Field Installation Guidelines

• Chassis Slot Placement: Slide the double-width module into the dedicated power supply slots on the far left of the RX7i backplane. Ensure complete engagement of the rear multi-pin connector prior to tightening the front faceplate retention hardware.
• Input Conductor Sizing: Implement heavy-gauge stranded copper conductors for the primary 24 VDC supply lines to minimize voltage drop across long terminal connections. Strip insulation back in strict alignment with terminal block depth limitations.
• Grounding Terminals: Secure an independent, low-impedance bonding jumper from the module front-panel ground stud directly to the main cabinet protective earth bar to establish effective surge protection thresholds.
