PRODUCT INFORMATION
Product Overview
The General Electric IC693PWR322 is a standard Power Supply for Series 90-30 PLC systems. This 30 Watt power supply operates with an input supply voltage range from 24 to 48 VDC. The unit delivers three distinct DC voltage outputs. These outputs include +5 VDC, +24 VDC isolated, and +24 VDC relay power. Backplane components draw power directly from the +5 VDC output bus. Relay circuits on Series 90-30 modules utilize the +24 VDC relay output. Attached 90-30 modules and input devices use the +24 VDC isolated output.
The power supply provides four front panel LED indicators for diagnostics. These status indicators include PWR, OK, RUN, and BATT LEDs. An integrated serial port supports RS-485 communication using a front access connector. Technicians use this port to connect programming workstations and handheld devices. The unit incorporates overvoltage protection set between 6.4 and 7 V for the +5 VDC output. It also offers overcurrent protection rated at 4 Amps maximum. A backup RAM battery slot retains controller memory during power outages.
