GE Fanuc IC694PWR321 PACSystems RX3i Power Supply Module
Configured for multi-rail power conversions in PACSystems RX3i expansion backplanes, the GE Fanuc IC694PWR321 (IC694PWR321 power supply module) provides direct physical execution of internal DC distribution. It converts wide-range AC or DC field supply feeds into three regulated output rails (+5 VDC logic, +24 VDC relay power, and isolated +24 VDC output) to energize local rack slots and external field devices without compromising system integrity.

PACSystems RX3i Backplane Power Architecture & Isolation Features
The IC694PWR321 interfaces with the RX3i expansion chassis to maintain stable backplane bus communication velocity across populated I/O racks. Operating across an AC input range of 85 to 264 VAC or a DC input range of 100 to 300 VDC, internal suppression circuits absorb line surges to defend downstream digital logic. Overcurrent limiting on the 5 VDC rail caps maximum draw at 4 A, triggering automatic output shutdown during direct short-circuit conditions to prevent backplane bus damage.
Frequently Asked Questions
Q: Can the IC694PWR321 module be hot-swapped while the expansion backplane is energized?
A: No, modules installed in expansion backplanes powered by the IC694PWR321 cannot be hot-swapped; power must be disconnected prior to inserting or removing hardware.
Q: What functions are unavailable when using the IC694PWR321 compared to a primary RX3i power supply?
A: The IC694PWR321 is designed specifically for expansion backplanes and does not provide an integrated serial communication port or battery backup support features.
Q: How does the internal power supply protection react when an overcurrent event occurs on the 5 VDC rail?
A: Integrated logic senses the current overload, turns off output regulation, and attempts continuous restart cycles until the excessive load or wiring fault is cleared.
Field Installation Guidelines
Slide the IC694PWR321 module into the designated power supply slot of an RX3i expansion chassis until the rear connector seats into the backplane. Tighten the terminal block screws to a torque limit of 1.3 Nm using copper conductors rated for at least 75 deg C. Wire source AC (120/240 VAC) or DC (125 VDC) feeds to the top terminal points, maintaining a dedicated low-resistance connection from the ground terminal to the main enclosure earth bus. Keep field supply wiring separated from sensitive analog input cables by at least 300 mm to suppress noise coupling, and close the terminal protective cover during normal operation to prevent shock hazards.
