Pepperl+Fuchs HiC System Isolated SMART Transmitter Power Supply (HiC2025)
The Pepperl+Fuchs HiC2025 is a high-performance, single-channel isolated barrier designed to power and interface 2-wire SMART transmitters or current sources located in hazardous areas. Part of the ultra-compact HiC System family, this module safely transfers an analog 4 mA to 20 mA signal from the field into the safe control room environment. By offering robust galvanic isolation between field loops, control systems, and power structures, it effectively safeguards expensive control elements like PLCs and DCS analog input cards against catastrophic ground loops and overvoltage surges.
Key Features
-
SMART Protocol & HART Compatibility: Supports bidirectional data communication superimposed on the 4 mA to 20 mA current loop, allowing digital HART diagnostic signals to pass transparently between field instruments and the control system.
-
Ultra-Compact, Space-Saving Profile: Built with a super-slim housing optimized for high-density termination board mounting, significantly minimizing cabinet footprint requirements compared to conventional DIN-rail barriers.
-
Single-Channel Analog Input Isolation: Features a dedicated, highly accurate 1-channel analog input loop configuration designed specifically for processing critical process variables like temperature, pressure, or flow.
-
Onboard Power Diagnostics: Outfitted with a bright front-panel green “PWR” LED indicator that provides immediate visual confirmation of active power status and module operational health.
-
Pluggable Termination Board Assembly: Features integrated retention clips and pin layouts for effortless snap-in mounting onto Pepperl+Fuchs termination boards, facilitating hot-swappability and dramatically accelerating field installation times.
