Details: LB3104A
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 and short-circuit line faults are detected.
The intrinsically safe inputs are galvanically isolated from the bus and the power supply.
