VEGA – VEGATRENN 141 – 4–20 mA HART Signal Barrier / Isolator

The VEGA VEGATRENN 141 (TRENN141.AxxxKxx) is a single-channel, loop-powered signal barrier that provides galvanic separation, intrinsic safety, and bidirectional HART communication for 4–20 mA sensors. Designed for hazardous locations, it supplies sensors intrinsically safely and enables full HART access via front sockets or terminals.
