GE IC694PWR321B RX3i 30 W AC/DC Power Supply

Supplies 30 W of backplane power to an IC694 serial expansion rack from a nominal 120/240 VAC or 125 VDC source.

Description and purpose

The IC694PWR321B is used in an IC694 serial expansion rack to convert the cabinet supply into the backplane power required by the installed I/O modules. Emerson identifies the IC694PWR321 family as a 30 W supply with nominal 120/240 VAC or 125 VDC input.

For users replacing a failed rack supply, the key checks are the backplane catalog number, actual cabinet input and total module load. A similar-looking IC695 universal-backplane supply is not the same installation. Confirm that the complete rack demand remains within 30 W before returning the expansion rack to service.

Before you orderSend the full IC694PWR321B label, the IC694 rack number, a photo of the input terminals and the installed module list. These details help verify the power source, rack type and available load margin.

What buyers should verify in the photos

Check that the full nameplate shows IC694PWR321B. Review the connector, terminal or port arrangement, enclosure condition and any revision markings visible on the label.

For an installed-system replacement, compare the photographed revision with the project hardware record and the unit being removed. Family appearance alone is not enough to confirm interchangeability.

Buyer tip: Request current front, side and connector photos before stock confirmation.
BUYER QUESTIONS

FAQ about GE IC694PWR321B

Will IC694PWR321B fit the expansion rack already installed in my machine?Use it only after confirming that the rack is an IC694-series serial expansion backplane. Do not choose it for an IC695 universal backplane based on appearance alone; check the rack catalog number and the complete supply nameplate.
Can I connect IC694PWR321B to the power source already available in my cabinet?Emerson lists nominal 120/240 VAC or 125 VDC input for IC694PWR321. Confirm whether the cabinet source is AC or DC, then compare the input terminals and protective-earth connection with the removed unit before wiring.
How can I tell whether the 30 W capacity is sufficient for my rack?Add the backplane power requirement of every module installed in the expansion rack. The total must stay within the 30 W capacity, with suitable engineering margin; do not judge adequacy from the number of empty slots alone.
Can IC694PWR321B directly replace an IC694PWR330 or an IC695 power supply?Do not assume direct interchangeability. Confirm the backplane family, input source, power-distribution requirement, complete catalog number and project hardware configuration. Similar input ratings do not prove that two supplies suit the same rack.
What should I check if the expansion rack loses power or repeatedly restarts?Check the incoming cabinet voltage, terminal tightness, protective earth, supply seating, backplane condition and total rack load. Also record when the reset occurs and which modules are active, because an overload or wiring fault can resemble a failed supply.
What should I send so the correct IC694PWR321B can be verified before shipment?Provide clear front and side nameplate photos, the IC694 rack model, actual AC or DC input, installed module list, fault symptoms, quantity and destination. This lets the replacement be checked against the real installation rather than the base number alone.
