ABB LDMUI-001 61320946C｜Input/Output Module｜

LDMUI-001 61320946C

Rectification unit collects and outputs all external signals
Digital input DI: 24V start stop, emergency stop, cabinet door interlock, cooling fan, external fault signal
Digital output DO: Fault alarm, ready, running, contactor driven relay circuit
Analog AI: Input voltage, DC bus voltage, rectified current 4-20mA sampling
Communication interface of operation panel
Onboard RS485, external CDP312R operation panel, enabling local fault viewing, modification of rectifier unit parameters, and start stop control
Hardware protection logic
Built in hardware blocking circuits for overvoltage, overcurrent, overtemperature, phase loss, and DC grounding, quickly blocking rectification pulses in case of faults
Whole machine fault diagnosis
Multiple sets of LED indicator lights on board, indicating power, communication, channel signals, and fault status respectively, quickly locating wiring/hardware faults
Interlocking communication inside the cabinet
Communicate with the main control board of the inverter unit through the backplane bus to achieve interlocking between the rectifier and inverter units
