VEGA – VEGATRENN 141 – Single-Channel HART Signal Barrier, Loop‑Powered, Ex‑Rate

The VEGA VEGATRENN 141 is a single-channel isolating barrier for 4–20 mA HART sensor loops in hazardous areas. Designed to provide galvanic separation between the field and control systems, it supports full bidirectional HART communication and operates as a loop-powered device—no external supply required. Ideal for Ex Zone 0/1 applications.
