Digital Input

Proximity switch Contact input /Transistor output

1 input 2 output

Overview

Isolated safety barrier at detection side: PHD-12TF-288, digital input and output, single input and dual output.

^ The isolated barrier can convert the proximity switch and contact input in the dangerous area to the transistor output signal and transmit it to the safe area. The output transistor between e-c is equipped with a selection switch of "inverted phase/normal phase" , in addition, there is a input signal short circuit or open circuit alarm indicator, the circuit provides for input sensor power supply.

^ This product needs an external 20-35VDC power supply.

^ The signal status indicator is set in red and yellow light to indicate the working status of the output relay, when it is for alarming then the light is red, during normal operation the light is yellow.

* Bus power supply, please see appendix for details.
