Overview
The base plate mounted isolated safety barrier PHD-11HP-23 can realize 1:1 transmission of frequency signals from hazardous area instruments to the safe area, and provide isolated power distribution power (24V) to the field instruments in the hazardous area.
This product requires external 20~35V DC power supply, power supply, input and output are isolated at three ends.
