Main Functions

1. Main‑rack power source, converts field 24/48VDC 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 program download and HMI communication channel for CPUs without onboard serial port.
3. Supports external backup‑battery to preserve real‑time clock and CPU RAM data during power‑off.
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 / short‑circuit alarm   ‑ BATT：Low‑battery warning indicator

Installation & Wiring Requirements

1. Cut off PLC main DC input power before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling power‑supply module.
2. Insert IC693PWR322 into far‑left dedicated power‑supply slot of main baseplate and lock latch; install external backup‑battery if needed.
3. DC 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 DC input, verify OK / FAULT / BATT 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; pay attention to battery health; full‑system power‑on commissioning test mandatory before unit put‑into‑service。
