3 Function

The isolating power Supplies are used in the operation of 2-wire and 3-wire transmitters or
to connect to intrinsically safe mA current sources.
The 2-wire and 3-wire transmitters are supplied with power by the transmitter power supply
unit. The devices bidirectionally transfer a superimposed HART communications signal.
