The core of automatic control is that the control unit must be reliably isolated from the sensors and actuators to avoid interference.
The core of automatic control is that the control unit must be reliably isolated from the sensors and actuators to avoid interference. The terminal can perform this function well and ensure that the field signal matches the low voltage required by the electronic control device.
It is the interface component between peripheral equipment and control, signal and regulator device for process control, and is suitable for different voltage and power ranges.
