PHD-22TP-1313 /PHD-22TP-2323
Overview
The frequency signal is input into the isolated safety barrier, which can realize the 1: 1 transmission of the frequency signal of the instrument in the hazardous area to the safe area, and provide the isolated power supply (12V or 24V) for the field instrument in the hazardous area.
This product needs independent power supply, and the power supply, input and output are isolated between each other.
