Functional Features High-precision sampling circuit collects real-time power parameters of rack power units. Hardware threshold comparison circuit judges abnormal power status. Digital data of power status transmits to Ovation controller through backplane bus. Relay contact outputs external alarm signal when power fault occurs. Front panel LED indicators display normal running state and fault alarm state. Standard plug-in rack structure supports hot swap under non-critical conditions.
Application Scenarios Ovation DCS main controller racks of thermal power plants and large chemical factories. It monitors operating status of redundant rack power supply modules.
Performance Parameters Sampling circuit maintains high measurement accuracy of voltage and current in full temperature range. Threshold comparison circuit responds rapidly once parameters exceed limit. Relay contacts achieve stable switching action for external alarm circuit. Backplane communication ensures stable upload of power monitoring data.
Material Composition Flame-retardant engineering plastic housing. Multi-layer flame-retardant glass fiber epoxy PCB. Precision sampling resistors, comparison chips, processing microprocessor, relay components and LED indicators. Gold-plated copper alloy backplane connector.
Structural Features Standard plug-in card for Ovation controller rack slots. Front panel equipped with power status LED and fault alarm LED. Guide rails and mechanical latches lock module inside rack. Rear gold-plated connector mates with Ovation rack backplane bus. External alarm relay terminals are arranged on front panel.
Working Principle Power signals from rack power supply transmit to sampling circuit of this module via rack backplane. Sampling circuit converts voltage and current signals into digital values. Onboard processor compares measured parameters with preset threshold values. When parameter exceeds safe range, relay contact switches state and fault information uploads to Ovation controller through backplane bus.
Installation Requirements Insert module along rack guide rail into designated controller rack slot and lock mechanical latch. Connect external alarm wiring to relay terminals on front panel. Use shielded cables for external alarm signal wiring. Keep ventilation path of rack unblocked. Set alarm threshold parameters in DCS engineering station after installation.
Precautions for Use Cut off rack power before module replacement. Backup threshold configuration parameters before parameter modification. Do not touch gold-plated backplane connector directly. Inspect relay contact condition during regular maintenance. Do not disassemble module housing.
