The Transmitter Power supply Unit and the Buffer Amplifier MUS80  are devices which are  used as peripheral interfaces to process control systems. The transmitter power supply unit supplies electronic transmitters in "two-wire design". Noise-free signal transmission is guaranteed by the galvanic separation of the device. The buffer amplifier separates signal circuits galvanically and prevents undesirable intermeshing and disturbances. Connecting transmitter power supply and buffer amplifier in series, the device can be used as a signal multiplier.  For this application, the device offers two galvanically separated outputs.
