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

The VEGA VEGATRENN 152 (TRENN152.AMXSKXX) is a dual-channel intrinsically safe signal barrier designed for separating 4–20 mA HART sensor loops in hazardous environments. It enables galvanic isolation between field and control equipment while supporting full bidirectional HART communication. With its loop-powered design, no external supply is required, making it ideal for Ex Zone 0/1 installations.

Key Features:

• Model: TRENN152.AMXSKXX

• Channels: 2 × 4–20 mA HART (passive loop-powered)

• Power Supply: 15–35 V DC (loop-powered)

• Voltage Drop: ≤5 V at 20 mA

• HART Support: Bidirectional communication via front sockets or terminals

• Intrinsic Safety: Ex-approved (ATEX, IECEx, SIL 2)

• Mounting: DIN-rail (35 mm), removable screw terminals

• Temperature Range: –20 °C to +60 °C

• Enclosure: IP20, compact profile ~113 × 52 × 20 mm
