PHG-11TC-33*

Communication signal input isolated safety barrier

1 input 1 output

Input :RS-485 Half Duplex Digital Signal

Output :RS-485 Half Duplex Digital Signal

    Overview

    PHG-11TC-33* communication signal input signal isolator can realize two-way communication of RS-485 half-duplex digital signals in the control room and on-site. The circuit provides power distribution for on-site instruments (as shown in the table below).
        This product needs to be powered independently, and the power supply, input and output terminals are isolated.

    Code Distribution voltage, current
    No No distribution power
    A 5V
    B 6V
    C 12V
    F 24V
    H Cutomizable
