Description
IC693PWR330 Product Overview
The IC693PWR330 is a 30 W plug-in power-supply module that occupies the left-most slot (slot 0) of every GE Series 90-30 PLC rack. It auto-ranges from 85–264 VAC, 47–63 Hz or 100–300 VDC and delivers three isolated DC outputs: +5 V (6 A) for logic, +24 V relay (0.8 A) for output-module coils, and an isolated +24 V (0.3 A) that can be used to power field devices or input modules

.
In the automation hierarchy the unit sits at the “backplane power” layer: it provides logic-level sequencing signals (ACFAIL#) and up to 6 A on the +5 V rail while riding through at least one AC line cycle (15 ms) without loss of output—enough to keep the CPU alive during upstream breaker transfers. Electronic over-current, over-voltage, and over-temperature protection are standard; faults are signalled by a front-panel green “FIELD OK” LED and can be cleared by removing the overload
.
Because the module is convection-cooled and certified for Zone 2 hazardous locations, it is widely used in turbine skids, compressor stations, and off-shore platforms where additional fans or external supplies are undesirable.

Core Features & Customer Value
Auto-ranging input – Accepts 85–264 VAC or 100–300 VDC without jumpers, so the same part number works worldwide and rides through plant battery float-voltage swings without nuisance shutdowns
Auto-ranging input – Accepts 85–264 VAC or 100–300 VDC without jumpers, so the same part number works worldwide and rides through plant battery float-voltage swings without nuisance shutdowns
.
Triple-rail in one slot – Delivers +5 V (6 A), +24 V relay (0.8 A), and isolated +24 V (0.3 A) from a single module, eliminating separate DC/DC bricks and their associated wiring, fusing, and heat
.
15 ms ride-through – Holds all outputs valid for at least one AC line cycle, bridging upstream breaker transfers and keeping the CPU alive during voltage dips
.
Convection cooling – No fan required up to 60 °C, reducing maintenance and allowing installation in sealed turbine or off-shore skids where forced air is impractical
.
Zone 2 / marine certification – ATEX, ABS, BV, DNV-GL, and LR approvals allow direct installation in hazardous-location panels without additional isolation transformers
.
Typical Applications
In combined-cycle power plants the IC693PWR330 is routinely installed in the left-most slot of Series 90-30 racks that govern gas-turbine fuel valves, inlet-guide-vane actuators, and cooling-water pumps. The 6 A +5 V rail powers the CPU and high-speed counter modules, while the +24 V relay output feeds the coils of output-relay modules

.
In pipeline compressor stations the same supply runs off 125 VDC battery, providing uninterrupted power to the anti-surge PLC and the +24 V transmitter excitation even during AC outages.
Because the module is certified for marine environments, it is also used on off-shore platforms for well-head control panels without needing additional HVAC or fans.
