Application
The double channel VEGATRENN 142 is used for galvanic separation, intrinsically safe power supply as well as signal transmission of Ex-approved 4 … 20 mA sensors in hazardous areas. The separate power supply ensures a reliable measured value transmission. VEGATRENN 142 is used in all industries als with Ex applications. The VEGATRENN 142 is suitable for bidirectional transmission of HART signals. The HART signal can be picked off via the HART communication sockets integrated in the front or the terminals. The complete HART permeability allows complete access to the sensor settings.
Benefits
- Simple installation though carrier rail mounting as well as detachable, coded terminals
- Complete HART permeability enables free access to sensor settings
- Universally applicable Ex separator for all 4 … 20 mA/HART sensors (use in Ex area is optional)
- For auxiliary voltage 20.4 … 34.1 V DC to supply the device and the connected sensors
