Overview
The switching input relay output signal isolator converts the input signal of the switch contact or proximity switch into a relay output through isolation. Line fault detection is through a separate relay output 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.
Specifications
