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.
