Product Performance

DU-2MKIII adopts high-precision AD conversion chip and digital filtering algorithm, with measurement data update rate of 1 time/second, ensuring real-time and accurate parameter monitoring. It supports custom display interface, and can configure display parameters, alarm thresholds and output logic through buttons or software, with convenient operation.

The high-contrast LCD screen has good visibility in strong light environments, and the backlight brightness is adjustable. Built-in surge protection circuit (compliant with IEC 61000-4-5) can resist 2kV transient overvoltage. Wide voltage power supply design adapts to power requirements of different scenarios, with mean time between failures (MTBF) ≥150,000 hours.

Relay alarm response time ≤100ms, which can accurately trigger sound and light alarm or linkage protection action. It communicates seamlessly with mainstream PLC and DCS systems via Modbus protocol, with data transmission delay ≤200ms, supporting data integration of centralized monitoring platform.
