Accepts the broad AC or DC input range documented for the serial-rack supply.
Product Overview
IC694PWR321 is the 30 W PACSystems RX3i power supply for serial expansion racks. Emerson identifies the input class as 120/240 VAC or 125 VDC.
The module supplies the rack through the dedicated power-supply position and provides the documented 5 VDC, 24 VDC relay and isolated 24 VDC output rails used by the backplane architecture.
The exact IC694PWR321 identity distinguishes this standard 30 W supply from the high-capacity serial-expansion supplies in the same platform family.

Features
Generates the multiple rails required by the compatible backplane.
Keeps the 30 W rack-load limit visible during spare selection.
Installs in the dedicated power-supply position rather than a normal I/O slot.
Applications
- Powering a supported PACSystems RX3i serial expansion rack.
- Replacement where the installed input source and complete rack load are documented.
- Legacy rack maintenance requiring the exact IC694PWR321 catalog identity.
- Planned outage work that includes input protection and conductor inspection.
Installation
- Calculate the complete rack load and confirm it remains within the documented supply budget.
- Isolate the AC or DC source and record terminal polarity, protection and grounding.
- Install IC694PWR321 only in the dedicated power-supply position and restore all covers.
- Energize under the approved procedure, then verify output health, rack recognition and stable I/O operation.

FAQ
What must be checked before ordering IC694PWR321?
Provide the power-supply label, backplane model, input source, complete module list, rack-load calculation and required quantity.
Can IC694PWR321 be chosen from rack fit alone?
No. Confirm input voltage, available 30 W capacity, output-rail loading, protection and backplane compatibility.
Does IC694PWR321 support redundant load sharing?
Do not design redundancy around this module unless an applicable Emerson system document explicitly approves the architecture.
What should be inspected when IC694PWR321 is removed?
Inspect input terminals, fuse or branch protection, earth connection, backplane connector and signs of heat or contamination.
What proves IC694PWR321 is ready for service?
Confirm correct input, stable supply indicators, clean rack diagnostics, adequate load margin and normal operation of all powered modules.
