Hybrid Analog + Digital Dual-channel Acquisition: Integrated multi-path analog input for excitation voltage, winding temperature, transformer auxiliary AC signal collection; multi-channel 24VDC digital input for breaker, relay, auxiliary contact on-off status monitoring.
Per-channel Galvanic Isolation Protection: Every signal channel built-in optocoupler isolation circuit, withstand 250VDC dielectric strength, effectively filter power grid surge and field interference to avoid sampling channel breakdown.
Backplane Parallel Bus Data Transmission: Matches proprietary ABB rack bus, high-speed real-time upload sampled data to main controller, supports system hot-plug identification without power-off modification.
Independent LED Channel Fault Indication: Separate power supply, communication, input channel abnormal indicator lamps, rapid on-site fault location without extra test equipment.
Built-in Multi-stage Anti-surge Circuit: Input terminal equipped TVS lightning protection, short-circuit interlock, single channel short fault will not damage adjacent circuit or main control unit.
24VDC Backplane Powered: Working power supplied from cabinet rack backplane, reverse polarity and overvoltage filtering design to adapt unstable field power supply.
