Function
The transmitter power supply feeds 2- and 3-wire transmitters.
Active signals from separately powered field devices and 4-wire transmitters can be connected.
Open circuit, short circuit, and Live Zero status are detected.
The input is galvanically isolated from the bus and the power supply.
