Features:

  • Backplane role: RX3i Serial Expansion power supply
  • Input flexibility: wide-range AC or DC source
  • Output structure: +5 V, relay +24 V, and isolated +24 V rails
IC694PWR321 powers a serial expansion rack rather than an RX3i Universal Backplane.

Its 30 W total and 15 W +5 V boundaries determine how the expansion modules are budgeted.

Input wiring, grounding, 24 V loading, LEDs, and the no-hot-swap rule form one installation and diagnostic record.

Availability of IC694PWR321 is subject to Apter Power inventory and sourcing confirmation.

  • The supply provides a maximum combined output of 30 W across its three output rails.
  • The +5 V DC output has a separate 15 W maximum within the combined output budget.
  • Relay +24 V DC and isolated +24 V DC rails serve distinct backplane loads and must be budgeted accordingly.
  • Select the documented AC or DC source range and wire the supply input according to the serial expansion backplane instructions.
  • Calculate the +5 V, relay +24 V, and isolated +24 V loads before installation so the combined demand remains within the 30 W capacity.
  • Coordinate backplane grounding, shutdown behavior, and expansion-cable placement with the RX3i rack configuration before power is applied.
  • The PWR indicator helps distinguish supply or source status during rack troubleshooting.
  • The OK and RUN indicators provide separate PLC-health and controller-run observations.
  • An overload or short on the isolated 24 V output can stop PLC operation; clear the fault before restoring service.
Description
General Electric IC694PWR321 is a 30 W power supply for a PACSystems RX3i Serial Expansion Backplane. It accepts either wide-range AC input or the documented high-voltage DC input, allowing the same supply to support the approved expansion-rack power source.

The unit converts incoming power into the +5 V logic rail, relay +24 V DC, and isolated +24 V DC services used by the expansion backplane and installed modules. Input-to-backplane isolation and ride-through capability help maintain predictable rack operation during normal industrial supply disturbances.

Load planning must keep the combined rail demand within the 30 W rating and the individual +5 V limit. Before exchange, verify the serial expansion backplane, incoming wiring, fuse, grounding, and the controlled shutdown sequence for every module in the rack.

Technical notes
Before replacing IC694PWR321, verify the Serial Expansion Backplane, source wiring, rail loading, common grounding, and shutdown requirements.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why can IC694PWR321 not be placed in an RX3i Universal Backplane?
The system manual assigns IC694 power supplies to Serial Expansion Backplanes; Universal Backplanes use the documented IC695 supply family.
How should the output budget for IC694PWR321 be calculated?
Keep all three rails within 30 W total and separately limit the +5 V load to 15 W while accounting for relay and isolated 24 V demand.
What wiring precaution applies when several racks use IC694PWR321 from one DC source?
Maintain identical source polarity at every supply and connect each backplane to a common system ground to avoid hazardous potential differences.
Which indicators help isolate an IC694PWR321 power or controller problem?
Use PWR for source and supply operation, OK for PLC health, and RUN for controller run state, then verify input and output measurements.
What happens if the isolated 24 V output of IC694PWR321 is overloaded?
The manual warns that an overload or short on that output can stop PLC operation; remove the fault and recheck the complete load budget.
Why must maintenance on modules beside IC694PWR321 be planned as a shutdown?
The Serial Expansion Backplane does not permit module hot insertion or removal, so isolate power and follow the approved rack procedure.
