Product features

High precision 24 bit AD measurement, feeding with sensor.

Maximum can provide 4 way alarm relay output control.

Standard MODBUS RTU communication

With signal conversion function

It can realize double output control of heating and refrigeration (refrigeration adopts relay, which can protect the function of refrigeration compressor)

Patent designed anti-interference chip design measuring circuit, can work in harsh working environment.

Improved DK PID algorithm control, output faster and no overshoot. Control speed 100MS
