VEGA – VEGATRENN 152 (TRENN152.AMXSKXX) – 2‑Channel HART Isolating Barrier

The VEGA VEGATRENN 152 (model TRENN152.AMXSKXX) is a compact 2-channel passive isolating barrier for intrinsically safe 4–20 mA/HART loops. It’s loop-powered (15–35 V DC) and supports full bidirectional HART communication, making it ideal to bridge Ex-approved sensors into non-Ex systems safely—certified for Ex zones and SIL 2 environments.
