GE IC693PWR321 Power Supply: Key Specs & Applications
GE IC693PWR321 Standard Power Supply Overview
The GE IC693PWR321 is a standard power supply module from the GE Fanuc Series 90-30 platform. It delivers up to 30 watts of power and accepts both AC and DC input voltages. This power supply occupies the leftmost slot of the baseplate and provides three separate outputs: 5 VDC, 24 VDC relay, and 24 VDC isolated. Engineers rely on this module to power the processing capabilities of the Series 90-30 PLCs efficiently.
Key Technical Specifications of the GE IC693PWR321
The IC693PWR321 supports an AC input range of 85 to 264 VAC with nominal values of 120-240 VAC. For DC input, the range is 100 to 300 VDC with a nominal value of 125 VDC. Its input power requirement is 90 VA with AC input and 50 W with DC input. The power supply handles an inrush current of 4 A peak for a maximum duration of 250 ms.
Output power capabilities include a maximum of 15 watts for 5 VDC and 24 VDC relay operation, 15 watts for 24 VDC relay, and 20 watts for 24 VDC isolated. Output voltages are 5.0 to 5.2 VDC (nominal 5.1 VDC), 24 to 28 VDC for the relay, and 21.5 to 28 VDC for the isolated output. Overvoltage protection activates at 6.4 to 7 VDC, and overcurrent protection limits at 4 A maximum. The holdup time is at least 20 ms.
Installation and Compatibility
Install the IC693PWR321 in the leftmost slot of the baseplate. The module is fully compatible with any CPU model in the Series 90-30 family. It carries cULus and CE certifications and operates in Class 1 Division 2 rated environments. A power supply limiting feature protects the hardware during direct shorts. The unit includes six terminals for operator connections and a smart switch fuse for protection.
Communication and Diagnostics
The IC693PWR321 includes one RS-485 serial port via a 9-pin sub-D connector. Operators use this port to connect peripheral devices or a CPU/computer. Enhanced diagnostics track all events and updates for operators. The module ships with an internal fuse (GE catalog number 44A724627-109), replaceable with Bussman 215-002 or Littelfuse 239-002.
This robust power supply ensures reliable operation in demanding industrial environments. Its dual AC/DC input flexibility and multiple output voltages make it a versatile choice for Series 90-30 PLC systems.
