WP-9000 Series Passive·DC Signal Converter

WP-9000 series passive DC signal converters isolate and transmit DC current signals. No need for additional power supply when in use. In practical applications, it can effectively solve the possible problems of signal interconnection, and at the same time can effectively suppress possible interference during signal transmission.

　　 This converter does not require external power supply, and the input circuit-the output circuit are electromagnetically isolated.
