Description
The single channel VEGATRENN 151 is used for galvanic separation of Intrinsically-Safe applications as well as the signal transmission of Ex approved 4 to 20 mA sensors in hazardous areas.
The separator is ideal in conjunction with signal conditioning instruments without own Ex approval.
The VEGATRENN 151 is suitable for bidirectional transmission of HART signals. The HART signal can be tapped via the front-mounted HART communication sockets or the terminals. The total transmissibility of HART signals allows unrestricted access to the sensor settings.
Features- Reliable separation of Intrinsically-Safe and non-Intrinsically-Safe circuits
- Simple installation, because no additional power supply is required (loop-powered)
- Simple mounting through carrier rail as well as detachable, coded terminals
