LB3002A2 HART Transmitter Power Supply Input Isolator
- 1-channel
- Power supply for 2- or 3-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
- HART communication also for separately powered devices
- Simulation mode for service operations (forcing)
- Line fault detection (LFD) and Live Zero monitoring
- Permanently self-monitoring
- Module can be exchanged under voltage
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.
