PHG-11TC-33*
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.
