Details: LB3105A2

Function

The transmitter power supply feeds 2-wire transmitters.

Active signals from separately powered field devices and 4-wire transmitters can be connected.

Open and short-circuit line faults are detected.

The intrinsically safe inputs are galvanically isolated from the bus and the power supply.
