Page 2: Functional Description
Analog mode: The analog output can be selected as current signal with (0)4-20 mA or as voltage signal (0)2-10 V. In the 4-20 mA mode and without any supplementary options, the NH3/ENH3 also works in the 2-wire technique. DGC-05_Bus mode: The transmitter can be connected to the GCD-05 system via the RS-485 interface. -
