Product Description
Product Overview Product overview
LYW-...P Series passive signal isolators do not require separate power supply—they draw power directly from the loop, enabling the isolator to operate efficiently while simultaneously converting and transmitting signals. This design achieves electrical isolation between the transmitter and the connected instruments or devices, safeguarding the transmitter in the process. As a result, it effectively addresses potential issues arising from signal interconnections and significantly enhances the system's resistance to interference.
