Mechanical Data

‑ Weight：approx 0.35 kg ‑ Dimension：Series‑90‑30 standard single‑slot power‑supply form‑factor ‑ Handling note：ESD‑sensitive power circuit; pay attention to internal backup‑battery aging during maintenance; replace fuse only with GE‑specified part number ‑ Terminal tightening torque：0.6‑1.0 N·m

Main Functions

1. Main rack power source, convert AC/DC field input into 5VDC logic bus, 24V relay‑drive and isolated 24V auxiliary power for main‑base CPU and I/O modules.
2. Integrated RS‑485 SNP‑X serial port, serves as programming/download and HMI communication channel for CPUs without onboard serial port.
3. Built‑in battery maintains real‑time clock and CPU RAM data during power‑off condition.
4. Hardware protective function for over‑voltage, over‑current and short‑circuit fault.
5. LED status indication on front panel:   ‑ Green OK：Power‑supply normal output indicator   ‑ FAULT：Over‑voltage / over‑current / fuse failure alarm

Installation & Wiring Requirements

1. Cut off PLC main input power before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling power‑supply module.
2. Insert IC693PWR321 into far‑left dedicated power‑supply slot of main baseplate and lock latch.
3. Main‑source power wiring strictly follow GE hardware manual; use suitable‑rating wire and external circuit breaker; separate power input cable from signal cables, connect protective ground reliably.
4. RS‑485 SNP‑X serial wiring: use shielded twisted‑pair, install terminating resistor at bus tail end.
5. After replacement：power‑on main input, verify OK / FAULT LED status; measure three DC output rail voltage; verify SNP‑X serial communication; calculate total 5VDC load consumption of all plug‑in modules.
6. Replacement note: Confirm main‑rack total power consumption within 30W rating; expansion racks cannot draw power from this power‑supply; inspect internal backup‑battery health; full‑system power‑on commissioning test mandatory before unit put‑into‑service。
