Functional Features High-precision sampling circuit collects real-time voltage and current data of rack backplane power. Communication circuit uploads power operation data and fault alarm information to DeltaV controller. Front-panel LED indicators display normal power state and fault alarm. Standard plug-in design supports hot swap under non-critical process operating conditions. Hardware over-limit detection circuit quickly identifies backplane power abnormality.
Application Scenarios DeltaV DCS main control racks and remote I/O racks in chemical plants, oil & gas facilities and pharmaceutical factories. It completes real-time power parameter sampling and power fault monitoring inside DeltaV equipment rack.
Performance Parameters Sampling circuit collects voltage and current data with high precision in full working temperature range. Fault detection circuit responds rapidly once electrical parameters exceed safe threshold. Communication circuit ensures reliable transmission of power status and alarm data. Circuit performance keeps stable under long-term cabinet vibration.
Material Composition Flame-retardant engineering plastic front panel. Multi-layer flame-retardant glass-fiber epoxy PCB. Power sampling chips, communication processing microprocessor and LED indicators. Gold-plated copper alloy backplane connector. Anti-oxidation plated copper power traces.
Structural Features Standard plug-in card for DeltaV rack slot. Front panel fitted with LED indicators for power running status and fault alarm. Guide rails and mechanical latch lock module firmly inside rack frame. Rear gold-plated connector mates with DeltaV rack backplane. PCB integrates power sampling circuit and signal processing circuit.
Working Principle Backplane power enters KJ2231X1-EB1 module through rear gold-plated connector. High-precision sampling circuit continuously measures backplane voltage and current value. Collected power data transmits to DeltaV controller through dedicated communication circuit. When power parameter exceeds preset safe threshold, module generates fault signal and uploads alarm message to DCS operator station.
Installation Requirements Cut off rack power supply before module installation. Insert module along rack guide rail into designated slot and lock mechanical latch. Confirm full engagement between module connector and rack backplane. Keep rack ventilation path unobstructed. Configure power monitoring parameters in DeltaV engineering workstation after hardware installation.
Precautions for Use Take anti-static protection when handling module. Do not touch gold-plated connector pins directly by bare hands. Inspect connector contact state regularly. Do not apply overvoltage to module power terminals. Do not disassemble module housing.
