Product Introduction
When a manufacturing line experiences intermittent power dips that cause PLC crashes and costly downtime, the GE Fanuc IC693PWR321 Standard Power Supply provides a stable and reliable solution. Part of the Series 90-30 PLC family, this power supply unit delivers up to 30 watts of total power and is designed to handle both AC and DC input sources. With a robust build and integrated protection features, it ensures continuous operation of your programmable logic controller in demanding industrial environments.
Technical Specifications Breakdown
The IC693PWR321 operates with an input voltage range of 85 to 264 VAC or 100 to 300 VDC, making it versatile for global installations. Its nominal rated voltage is 120/240 VAC or 125 VDC. Input power consumption is 90 VA with AC input and 50 W with DC input. The module provides three outputs: 5 VDC (15 watts maximum), 24 VDC Relay (15 watts maximum), and 24 VDC Isolated (20 watts maximum). Holdup time is 20 milliseconds minimum, ensuring ride-through during brief power interruptions. Inrush current is limited to 4A peak for a maximum of 250 milliseconds.
Industry Applications
This power supply is ideal for factory automation lines where consistent power to the PLC is critical. For example, in a packaging facility with high-speed conveyors and multiple sensors, the IC693PWR321 powers the CPU and I/O modules, maintaining uptime even when line voltage fluctuates. Its RS485 communication port allows connection to operator interfaces or SCADA systems for remote monitoring. The ability to accept either AC or DC input simplifies integration in plants with mixed power distribution.
Installation & Setup Guidance
Install the IC693PWR321 in the leftmost slot of the baseplate as specified for Series 90-30 racks. Ensure that the input voltage source is within the rated range of 85 to 264 VAC or 100 to 300 VDC. Use the provided 6-terminal connector for power wiring. The RS485 serial port (9-pin sub-D connector) can be connected to peripheral devices or a programming computer. Always verify that the total load on each output does not exceed the maximum ratings: 15 watts for 5 VDC, 15 watts for 24 VDC Relay, and 20 watts for 24 VDC Isolated.
Maintenance & Reliability
Regular inspection of the power supply is recommended to ensure reliable operation. Check for any signs of overheating or physical damage. The internal fuse (GE catalog number 44A724627-109) can be replaced with equivalent fuses such as Bussman 215-002 (GDC-2 or GMC-2) or Littelfuse 239-002. The module includes overvoltage protection (6.4 VDC to 7 VDC) and overcurrent protection (4A maximum) to safeguard connected equipment. Periodic testing of the holdup time (20 ms minimum) helps confirm readiness for power disturbances.
Compatibility & Integration
The IC693PWR321 is fully compatible with any CPU model in the Series 90-30 PLC family. It communicates via the built-in RS485 serial port, supporting protocol RS485 for connection to programming devices, HMIs, or other serial devices. The power supply integrates seamlessly into existing 90-30 racks, providing the necessary voltages for CPU and I/O modules. Its dual-input capability allows use in facilities with either AC or DC power systems.
Buying Guide
Before purchasing the IC693PWR321, verify that your system requires a 30-watt power supply and that the input voltage matches your plant supply (85-264 VAC or 100-300 VDC). This product is discontinued/obsolete, so please confirm current availability with SpareTechPLC before ordering.
