Overview
The Pepperl+Fuchs HiD2081 Safety Barrier is part of the H-System series of termination board-mounted intrinsic safety modules. It provides galvanic isolation and powers thermocouples, RTDs, potentiometers, or voltage-input devices located in hazardous areas. Moreover, the module linearizes the sensor signal and converts it into a standard 4–20 mA current loop or 1–5 V voltage output for safe-area control systems. In addition, the HiD2081 features sensor break detection and line fault detection (LFD), enabling reliable diagnostics and improved operational safety.
Engineers value the HiD2081 for its compact termination-board mounting design and functional safety performance up to SIL 2 (SC 3) according to IEC/EN 61508. Therefore, it is widely used in oil, gas, chemical, and pharmaceutical industries where intrinsic safety, precise measurement, and long-term reliability are essential.
