HART Transmitter Power Supply, Input Isolator LB3005A2

4-channel
Power supply for 2-wire transmitters with 4 mA … 20 mA
Installation in Zone 2 or safe area
Supply circuit 15 V (20 mA)
Input from active signals of 4-wire transmitters
HART communication via field bus or service bus
Simulation mode for service operations (forcing)
Line fault detection (LFD): one LED per channel
Permanently self-monitoring
Module can be exchanged under voltage

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 inputs are galvanically isolated from the bus and the power supply.
