哈尔滨LYW-...G Series Passive Signal Isolator
Application 1: Receive the current signal output from the four-wire transmitter on-site, isolate it, and then output it to the system;
Application 2: Alternatively, receive the current signal output by the system, isolate it, and then send it to the field-mounted valve positioner or electrical converter.
In both application modes, the energy consumption during operation comes entirely from the input circuit.

Product Description
Product Overview Product overview
The LYW series passive signal isolators require no external power supply and are primarily designed to provide electrical isolation between transmitters and the connected instruments or devices, safeguarding the transmitter in the process. They effectively address potential issues arising from signal interconnections while significantly enhancing the system's resistance to interference.
