Overview
Surge protection switch input transistor output signal isolator converts the input signal of the switch contact or proximity switch into a transistor output through isolation.
Line fault detection is output through a separate relay and displayed by an LED light on the top of the module. The switch of the module is used to select the phase of the channel and whether the line fault detection function is required.
This product needs to be powered independently, and the power supply, input and output terminals are isolated.
