Interface & Configuration

• Front Panel: Status LEDs (PWR, OK, FAULT)

• Backplane: Gold‑finger connector for 24 VDC input and ±15 V output

• Configuration: No DIP switches; fixed output voltages

• Diagnostics: LED status indication, overtemp/overcurrent fault logging

Core Functions

• Dual Voltage Regulation: Convert 24 VDC to stable ±15 VDC for analog circuits

• Isolation & Filtering: Isolate input/output, suppress noise for precision signals

• Fault Protection: Overcurrent/overvoltage/thermal shutdown safeguards loads

• System Monitoring: Real‑time LED status for power health diagnostics

Application Scenarios

• Process Industries: Pulp & paper, cement, metallurgy (legacy ABB CS 31/DCS)

• Power Plants: Advant DCS control room analog I/O power supply

• Precision Automation: HKQCS systems, servo amplifiers, signal conditioning

• Legacy System Retrofit: Replacement for aging 086370‑001 units in CS 31 racks

Usage & Maintenance

• Installation: Insert into designated rack slot, secure front screws

• Wiring: 24 VDC input via backplane; ±15 V output to analog modules

• Configuration: No setup required; powers up with correct voltages

• Maintenance: Monthly LED check; quarterly connector inspection; annual load test

• Replacement: Use identical 086370‑001; confirm input voltage range before power‑on
