MEP-SH digital PID operator regulator
MEP-SH digital PID operator regulator is an PID operator with manual/automatic switching function. Generally connected between the regulating device and the actuator (valve).
When in automatic mode, the valve opening is controlled by adjusting the input signal, and when in manual mode, the valve opening is controlled by the operating amount given by the instrument panel.
One channel regulation signal input, matched with DC current or DC voltage signal.
One measurement signal or valve feedback signal input. It can be equipped with potentiometer signals (valve feedback), DC current, DC voltage, thermal resistance, thermocouples, etc.
There are two types of operation output signals for actuators (valves): current output and relay output,
Used for actuators that receive 4-20mA signals and valves that directly control opening through forward/reverse rotation.
Operate the upper and lower limit limiting functions of the output.
Power on status setting function.
Adjust the input signal disconnection processing function.
Optional manual/automatic external switch control function.
Optional external transmitter power supply.
Optional manual/automatic status output, alarm output, tracking, and transmission output functions.
Optional communication interface, in addition to reading data, control output and manual/automatic switching can be achieved through the communication interface.
