AC and DC Input Flexibility

The GE Fanuc IC693PWR321 offers outstanding input flexibility. You can power it from standard AC mains (85 to 264 VAC). This covers 120VAC and 240VAC systems worldwide. You can also power it from a DC source (100 to 300 VDC). This is perfect for battery-backed or DC-only industrial sites. The IC693PWR321 automatically handles either input type. No jumpers or switches are required.

Output Power Distribution

This GE Fanuc IC693PWR321 provides three distinct output voltages. The +5 VDC output (15W) powers the CPU and backplane logic. The +24 VDC isolated output (20W) provides external power for certain I/O modules. The +24 VDC relay output (15W) powers relay circuits. Each output has protection against overcurrent and overvoltage. The hold-up time of 20 milliseconds keeps the system running through brief power dips.

Installation and Wiring Guidelines

Proper installation of the GE Fanuc IC693PWR321 ensures reliable system operation. Follow these key points.

• Baseplate Location: Install the power supply in the leftmost slot. This is the only valid position for Series 90-30 power supplies.

• AC Wiring: Connect line and neutral to the appropriate terminals. Use proper wire gauges for 85-264 VAC.

• DC Wiring: Connect positive and negative leads for 100-300 VDC input.

• Grounding: Connect the ground terminal to a good earth ground.

• RS485 Port: Use the 9-pin sub-D connector for programming and peripheral connections. Connect to a CPU or computer.

• Fuse Replacement: Use a Bussman 215-002 (GDC-2) or Littlefuse 239-002 as a replacement fuse.

• Compatibility: This power supply works with any Series 90-30 CPU model.
