The repeater power supply with plug-in connection technology supplies the transmitter in the field and electrically isolates the input signal from the output signal. HART data protocols can be transmitted bidirectionally. The device can be used in both isolator and repeater power supply operation. Electrically isolated 0 ... 20 mA or 4 ... 20 mA standard analog signals are available on the input and output sides with a maximum output load of 600 Ω. The measuring transducer supports fault monitoring and NFC communication.
