Product details

The WP-9000 series passive DC signal converter isolates and transmits DC current signals. No additional power supply is required during use. In practical applications, it can effectively solve the problems that may occur in signal interconnection, while effectively suppressing possible interference during signal transmission.


This converter does not require external power supply, and there is electromagnetic isolation between the input circuit and the output circuit.
