Working Principle

Three independent voltage sampling circuits continuously measure each chassis 24VDC power branch voltage levels, comparing against factory-calibrated fault thresholds. All power fault event data is stored in non-volatile memory powered by internal CR-1/2 AA-CB lithium backup battery during main power outage. Real-time power status and fault logs transmit to main HIMA safety CPU via isolated backplane bus. Daily automatic battery discharge test verifies backup cell capacity, triggering battery replacement alarm upon capacity degradation below rated threshold.

Advantage Highlights

1. Three-channel independent power monitoring supports triple redundant chassis power supply architectures
2. Long-duration backup battery retains critical safety fault logs through extended main power outages
3. SIL 3 certified full diagnostic coverage for chassis power supply integrity
4. Hot-swap compatible design eliminates full rack shutdown for module replacement
5. Daily automatic battery health testing enables predictive maintenance scheduling

Applicable Industries

Offshore Oil Platform ESD Systems, Large LNG Terminals, Thermal & Combined-Cycle Power Plant Safety Control, Petrochemical Mega-Plant SIS Racks, Hazardous Chemical Batch Production Safety Instrumented Systems

Installation Requirements

1. Install exclusively in dedicated auxiliary CPU adjacent slots of HIMA F-series redundant safety chassis
2. Insert CR-1/2 AA-CB factory-specified lithium battery before commissioning module
3. Maintain minimum 20mm ventilation gap around module for heat dissipation
4. Anti-static wristband mandatory during module installation and battery replacement operations

Usage Precautions

1. Replace internal lithium backup battery every 4 calendar years per factory service specification
2. Perform full power loss simulation test during annual SIS proof testing cycles
3. Use only original HIMA CR-1/2 AA-CB battery cells; third-party batteries invalidate SIL safety certification
4. Avoid installation in environments with corrosive gas, salt fog or continuous temperature cycling exceeding ±70°C range
5. Record all battery replacement dates in site safety equipment maintenance log for regulatory audit traceability
