According to the action mode, it can be classified into switching type and regulating type. The switch type is to connect the power supply directly and complete the switch action through the positive and negative directions of the switch. The regulating type takes the power supply as the power source and receives the parameter value 4~20mA (weak current control such as 0~5) signal preset by the industrial automation control system to complete the regulating action.
