PHG-11TC-33+

Surge protection type communication signal input signal isolator

1 input 1 output

Input :RS-485 Half Duplex Digital Signal

Output :RS-485 Half Duplex Digital Signal

    Overview

    The communication signal of PHG-11TC-33+ is the isolated safety barrier  with surge protection function, which can realize the two-way communication of  RS-485 Half Duplex digital signal in the control room and on site. 
    This product needs independent power supply, and the power supply, input and output are isolated.
