Overview
H serie backplane mounting isolated safety barriers at operating side: PHC-11HF-14, digital input and output, single input and single output.
Safety barrier can convert the input quantity of contact switch and logic level in safety area into the driving quantity of intrinsically safe equipments, and output it to the field of dangerous area, so as to
control solenoid valve, audible and visual alarm, etc.
The status indicator has red and yellow light colors, when alarm then the light is red, when it is with the output solenoid valve, then the light is yellow.
This product needs independent power supply.
