GE IC693PWR321U Power Supply Module
Product Overview
The GE IC693PWR321U is a power supply module designed for GE’s Series 90-30 PLC systems, a key platform in industrial automation. This module provides stable electrical power to other Series 90-30 components, such as CPUs, I/O modules, and communication modules, ensuring they operate reliably. It acts as the “power source” of the PLC system, making it essential for keeping automated processes running without interruptions.
As part of the IC693 Series, the GE IC693PWR321U fits into Series 90-30 backplane racks like the IC693CHS393. It connects to the rack’s power slot, converting incoming AC voltage into the DC voltages needed by the PLC’s internal components. The IC693PWR321U supports an input voltage range of 100–240 V AC, making it compatible with different electrical systems worldwide. It outputs 5 V DC and 24 V DC—the standard voltages required by most Series 90-30 modules.
Built for tough industrial environments, the GE IC693PWR321U operates in temperatures from 0°C to 60°C and humidity up to 95% (non-condensing). It resists dust, vibrations, and voltage fluctuations, working reliably in factories, automotive plants, and food processing facilities. Even though GE no longer manufactures it, the GE IC693PWR321U remains vital for maintaining older Series 90-30 systems, helping businesses avoid the cost of upgrading entire power systems.

Main features and advantages
Stable power output: The IC693PWR321U provides consistent 5 V DC (3.5 A) and 24 V DC (1.5 A) outputs. This stability ensures that sensitive components like CPUs and I/O modules work correctly, even when the main power fluctuates.
Wide input range: It accepts 100–240 V AC input. This means it can be used in countries with different electrical standards, from 110 V in the US to 220 V in Europe, without needing a voltage converter.
Built-in protection: The module has overcurrent and short-circuit protection. If a module draws too much current or a wire accidentally touches metal, the IC693PWR321U shuts down temporarily. This prevents damage to the power supply and connected components.
Tough design: The IC693PWR321U works in harsh conditions. It handles temperatures from 0°C to 60°C and high humidity. Dust and vibrations do not affect its performance, making it reliable in factories, outdoor installations, and dirty environments.
Easy to install: It fits into the power slot of Series 90-30 backplane racks. No special tools are needed. Simply slide it into the slot until it clicks. This makes replacing an old power supply quick and straightforward.
Compatibility: The IC693PWR321U works with all Series 90-30 modules. It can power a mix of digital I/O, analog modules, and communication cards, making it flexible for different system setups.

Installation and maintenance
Pre-installation preparations: Check that the IC693PWR321U fits your Series 90-30 backplane rack (like the IC693CHS393). Ensure the rack’s power slot is empty. Turn off the main power to the control cabinet. Slide the module into the power slot until it locks into place. Connect the AC power cable to the module’s input terminal. Make sure the cable is tight to avoid loose connections.
Maintenance suggestions: Inspect the IC693PWR321U regularly. Wipe dust off with a dry cloth to prevent overheating. Check the power cable connection to ensure it is secure—loose cables can cause power cuts. If the module’s status light is red (indicating a fault), turn off the main power. Remove the module and reinsert it to fix possible loose connections. If the fault remains, replace it with a spare IC693PWR321U. Store spares in a dry, cool area (10–30°C) to keep them in good condition.
Application fields
The GE IC693PWR321U is used in all industries that rely on Series 90-30 PLC systems:
- Manufacturing: In automotive factories, it powers the CPU and I/O modules that control assembly lines. It ensures robots, conveyor belts, and welding machines get steady power, keeping production on schedule.
- Food processing: It supplies power to PLC components in bottling lines and packaging machines. Its ability to handle washdowns and humidity makes it suitable for clean environments where food safety is key.
- Water treatment: In treatment plants, the IC693PWR321Upowers the PLC system that controls pumps and valves. It works reliably in damp, chemically exposed areas, ensuring water filtration and distribution run smoothly.
- Material handling: In warehouses, it provides power to the PLC modules managing conveyor systems and automated storage. Stable power keeps goods moving efficiently, reducing delays in shipping.
