Frequency transmitter; the input frequency pulse signal is isolated and converted into a current or voltage signal output. Requires independent power supply, with three-port isolation between input, output and power supply, and online fault self-diagnostics; the frequency range and fault output mode can be configured via PC or handheld programmer.
