Features

◆ Can be connected to intelligent control modules: conversion of optically isolated contact signal outputs, including programmable DO output function

◆ MCU microprocessor controller for stable and reliable performance

◆ Fault self-diagnosis function: protection and detection of the working state and operation of the intelligent controller itself

◆ Pre-alarm function, overload indication: when the load current reaches or exceeds a fixed value, it is equivalent to the light guide column exporting the light source

◆ Temperature monitoring and protection function: when the ambient temperature exceeds the set value (default setting 85°), the controller will output an alarm photoelectric signal or make the circuit breaker break
