Overview
Base plate mounted isolated safety barrier PHC-11HF-34 can convert the safety zone contact switch, logic level input into intrinsically safe equipment drive quantity, output to the hazardous area site, so as to control solenoid valves, acoustic and visual alarms and so on. Signal status indicator set red and yellow dual-color, alarm display red, output solenoid valve and other work display yellow.
The product needs independent power supply, power supply, input and output are isolated at three ends.
Main technical parameters
