Tutto sui PLC: la CPU
A practical engineering guide to PLC CPU operation, from deterministic scan cycles and I/O image tables to memory, communications, diagnostics, redundancy, processor sizing, and reliable system...
The IC693PWR331 is a 30-watt, wide-range DC input High Capacity power supply specifically designed for the GE Fanuc Series 90-30 PLC. It operates on a 24 VDC nominal input and is engineered for applications requiring higher +5 VDC current capacity than standard supplies, allowing the full 30-watt output to be consumed by the +5 VDC rail. This module is a "High Capacity" version, meaning it provides robust power distribution for demanding processor and I/O configurations within a single rack.
The IC693PWR331 features a flexible hardware architecture to support various Series 90-30 system requirements:
| Feature | Details |
| Model | IC693PWR331 |
| Nominal Rated Voltage | 24 VDC |
| Input Voltage Range | Run: 12 to 30 VDC Start: 18 to 30 VDC |
| Maximum Input Power | 50 W at full load |
| Total Output Power | 30 W maximum combined output |
| +5 VDC Output | 5.0 to 5.2 VDC, 30 W maximum |
| +24 VDC Isolated Output | 19.2 to 28.8 VDC, 20 W maximum |
| +24 VDC Relay Output | 19.2 to 28.8 VDC, 15 W maximum |
| Holdup Time | 10 ms minimum |
| Operating Temperature | Derating required above 50 deg C |
Can I use the full 30 watts just for the PLC rack modules?
Yes. For applications requiring significant +5 V current, the supply allows the full 30 W to be drawn from the +5 VDC output if other rails are lightly loaded.
What happens if the isolated 24 VDC output is shorted?
If the isolated +24 VDC output is overloaded or shorted, the controller stops operation to protect the system.
Why will the power supply not start at 15 VDC?
The unit can operate down to 12 VDC after startup, but requires at least 18 VDC during initial power-up.
