GE IC693PWR331 – High-Reliability AC Power Supply Module | Series 90-30 PLC Platform
Engineering Background
The GE Fanuc IC693PWR331 is a standard AC input power supply module designed for the Series 90-30 programmable logic controller platform — one of the most widely deployed mid-range PLC architectures in global industrial automation. Originally developed under GE Fanuc Automation and subsequently transitioned to GE Intelligent Platforms (now Emerson), the Series 90-30 system remains a backbone controller in process, discrete, and hybrid manufacturing environments worldwide.
Product Positioning
The IC693PWR331 serves as the primary power source for Series 90-30 CPU and I/O baseplate assemblies. It accepts standard 120/240VAC utility power and delivers regulated 5VDC and 24VDC bus power to the backplane, supporting full-rack configurations. For procurement engineers managing legacy system maintenance, expansion projects, or spare-parts inventory, the IC693PWR331 represents a critical, long-lead-time component that demands verified sourcing.

- Drop-in Replacement Compatibility — Direct form-fit-function replacement for existing IC693PWR331 installations; no firmware or configuration changes required
- Proven MTBF — Long field service history across millions of installed Series 90-30 systems globally
- Compact Single-Slot Footprint — Maximizes available I/O slots on 5-slot, 10-slot, and expansion baseplates
System Architecture & Signal Flow
The IC693PWR331 installs in the leftmost slot of any Series 90-30 baseplate (5-slot: IC693CHS391; 10-slot: IC693CHS392; expansion: IC693CHS393/398). AC mains connect to the module’s terminal block. The module converts and regulates AC input to +5VDC backplane bus power (logic supply) and an isolated +24VDC rail (field device supply). The CPU module (e.g., IC693CPU374) and all I/O modules draw from the 5VDC bus; field-side 24VDC sensors and actuators may draw from the isolated 24VDC output. A single green PWR LED provides local health indication. No external fusing is required for the backplane bus; however, field wiring to the 24VDC output should be protected per local electrical codes (IEC 60364 / NEC).
Sourcing & Quality Verification
Konmask.com sources IC693PWR331 modules through established industrial automation distribution channels. Each unit undergoes the following verification process before shipment:
- Visual inspection for physical damage, corrosion, and counterfeit indicators
- Label and date-code verification against known-good reference units
- Functional power-on test: input voltage application, output voltage measurement on 5VDC and 24VDC rails
- Backplane connector pin inspection (no bent pins, no oxidation)
- Anti-static packaging with humidity indicator card
Certificates of conformance and test reports are available upon request for regulated industries (pharmaceutical, defense, utilities).

Technical FAQ
Q: Is the IC693PWR331 compatible with all Series 90-30 baseplates?
A: Yes. It is compatible with all standard Series 90-30 baseplates including IC693CHS391 (5-slot), IC693CHS392 (10-slot), IC693CHS393, and IC693CHS398 expansion racks.
Q: Can the IC693PWR331 power a full 10-slot rack with all I/O modules populated?
A: The 30W total output capacity must not be exceeded. For high-density I/O configurations, calculate total backplane current draw from all installed modules. If the 5VDC load exceeds 4.0A, a second power supply or a higher-capacity unit (IC693PWR321 — 40W) should be considered.
Q: What is the difference between IC693PWR331 and IC693PWR321?
A: The IC693PWR331 provides 30W total output (4.0A @ 5VDC, 0.8A @ 24VDC). The IC693PWR321 provides 40W total output (6.0A @ 5VDC, 1.0A @ 24VDC). Both accept 120/240VAC input. Select based on total backplane power budget.
Q: Does this module support hot-swap replacement?
A: No. The Series 90-30 power supply must be replaced with the rack de-energized. Always follow lockout/tagout (LOTO) procedures before servicing.
Q: What warranty is provided?
A: Konmask provides a 90-day functional warranty on all verified units. Extended warranty options are available — contact us for details.
Q: Can you provide documentation or datasheets?
A: Yes. GE Fanuc Series 90-30 PLC Hardware Reference Manual (GFK-0356) and the IC693PWR331 datasheet are available upon request.
