Product Overview
Downtime on a Series 90-30 line rarely waits for a purchase order. The GE IC693PWR330H is the high-capacity AC/DC input power supply built for that rack, delivering three regulated outputs from a single leftmost-slot module. Emerson now owns the line, but the original GE Fanuc / GE Intelligent Platforms design remains the reference for plants running Series 90-30 hardware.
This is the revision H unit. It accepts 120/240 VAC or 125 VDC nominal input and holds up to 20 ms minimum during brief supply interruptions, so short dips do not drop your processor.
Technical Specifications
What the Three Outputs Actually Power
The 5 VDC output delivers 30 W maximum (5.0 to 5.2 VDC) for the backplane logic. The isolated 24 VDC output provides 20 W maximum (21.5 to 28 VDC) for field devices needing separation from logic ground. A separate 24 VDC relay output adds 15 W maximum (24 to 28 VDC) for relay coils and discrete loads.
Wide Input Window Solves Voltage Sourcing Problems
With an AC range of 85 to 264 VAC and a DC range of 100 to 300 VDC, the IC693PWR330H tolerates the sag and swell common on older plant feeds. Input power draw is 90 VA (AC) or 50 W (DC). Inrush current peaks at 4 A for 250 ms maximum, which matters when several supplies energize on the same breaker.
Thermal Envelope
Operating temperature is 0 to +60°C ambient. Weight is approximately 0.68 kg. Mounting location is the leftmost slot of the baseplate — not a spare slot.
Replacement and Upgrade Path
Because this supply is discontinued (End of Sale, last verified 2026-09), replacement planning is the real engineering task. Match the three output budgets before you swap: 30 W at 5 VDC, 20 W isolated at 24 VDC, and 15 W relay at 24 VDC. Undersizing any rail causes intermittent faults that look like logic problems.
For plants standardizing on Series 90-30, keeping a ready-to-ship spare on the shelf is cheaper than expedited freight during a shutdown. Oil AutoTech supplies fast-dispatch spares for oil, gas and industrial automation applications, with hands-on technical selection help when you need to confirm a fit.
Installation Notes
Seat the module in the leftmost baseplate slot and confirm the backplane connector is fully engaged. Verify input wiring matches your actual supply — AC versus DC — before energizing. Allow clearance for convection cooling; the 0 to +60°C rating assumes ambient air at the module, not inside a closed cabinet corner.
Maintenance and Reliability
Inspect periodically for loose terminal connections, dust accumulation on the housing, and discoloration near input terminals. Heat is the main wear factor, so keep cabinet filters clean and confirm ambient stays inside the rated window. Log any hold-up-related dropouts; repeated events point to upstream supply problems rather than the module itself.

No. It is discontinued (End of Sale), last verified 2026-09. Availability depends on remaining stock, so confirm with Oil AutoTech.
Can it run on DC power only?
Yes. Nominal input includes 125 VDC, with a DC range of 100 to 300 VDC and 50 W input power.
Which slot does it occupy?
It mounts in the leftmost slot of the baseplate.
What is the hold-up time?
20 ms minimum, which covers brief supply interruptions.
How much 24 VDC is available?
20 W maximum isolated (21.5 to 28 VDC) plus 15 W maximum relay (24 to 28 VDC).
