Mechanical Data

‑ Weight：approx 0.36 kg ‑ Dimension：Series‑90‑30 standard single‑slot power‑supply form‑factor ‑ Handling note：ESD‑sensitive power circuit; battery must be purchased separately; check battery aging status during maintenance ‑ Terminal tightening torque：0.6‑1.0 N·m

Main Functions

1. Main‑rack high‑capacity DC power source, convert field 24 VDC input into +5 VDC logic bus, +24 V relay‑drive and isolated auxiliary 24 V power for CPU and all back‑plane modules; support full 30W power assigned to +5 V bus for heavy‑load main‑rack.
2. Integrated RS‑485 SNP‑X serial port, serves as program download and HMI communication channel for CPUs without onboard serial port.
3. Cooperate with external backup‑battery, preserve real‑time clock and CPU RAM data upon power‑off.
4. Built‑in hardware protection 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 fault 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 IC693PWR331C into far‑left dedicated power‑supply slot of main baseplate and lock latch; install external backup‑battery if needed.
3. DC‑input power wiring strictly follow GE hardware manual; match proper‑rating wire and external circuit‑breaker; separate power input cable from signal cables, reliable protective‑ground connection.
4. RS‑485 SNP‑X 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 each 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 battery health; full‑system commissioning test mandatory before unit put‑into‑service。
