VEGA – VEGATRENN 142 (TRENN142.AXXXKXX) – 2‑Channel HART Barrier

The VEGA VEGATRENN 142 (TRENN142.AXXXKXX) is a double-channel signal isolator designed to integrate intrinsically-safe 4–20 mA/HART sensor loops into safe-area control systems. It provides loop-powered galvanic isolation, ATEX/IECEx approvals, SIL 2 safety, and full bidirectional HART transparency via front sockets or terminals. Ideal for hazardous-area installations requiring uncompromised signal integrity and access.
