Overview
The PHG-11TC-33M is signal isolator with communication signal , which can realize the two-way communication of RS-485 Half Duplex digital signal in the onsite and control room. The circuit provides power distribution for on-site instruments. The voltage value can be switched through the top dial switch. The specific operation method is shown in the chart below.
This product needs independent power supply, and the power supply, input and output are isolated.
