VEGA – VEGATRENN 142 – 2‑Channel HART Signal Barrier, Loop‑Powered, Ex‑Rated
The VEGA VEGATRENN 142 (TRENN142.AXXXKXX) is a dual-channel isolating barrier for integrating 4–20 mA HART loops from hazardous zones into safe-area control systems. It provides galvanic isolation, supports bidirectional HART communication, and requires no external power due to its loop-powered design. Suitable for Ex Zone 0/1 applications, with SIL 2 certification for safety-critical processes.
