Pepperl+Fuchs HiC2025 SMART Transmitter Power Supply 1ch isolated barrier 24VDC

Product Positioning
The HiC2025 is a classic model in the Hi series isolation barrier from Pepperl+Fuchs, Germany. It is designed to provide intrinsically safe power and signal isolation for two-wire smart transmitters (supporting HART/BRAIN protocols) in hazardous locations such as Zone 0, Zone 1, and Zone 2. It converts 24 V DC loop power into a safe 4-20 mA signal and provides 2.5 kV three-way isolation (input, output, and power) between the hazardous and safe areas of the field, ensuring reliable system operation and the safety of personnel and equipment.

Core Features
• Intelligent Communication: Bidirectional digital signals are transmitted without loss. HART, BRAIN handheld communicators, or AMS device management systems can communicate directly with field transmitters from the control room, enabling remote configuration, diagnostics, and asset optimization.
• High-Precision Conversion: Typical transmission error ≤ 0.1% and temperature drift ≤ 50 ppm/K meet the needs of high-precision process control. • Fail-Safe: Built-in short-circuit, reverse polarity, overload, and line-break protection; SIL 2/SC 3 functional safety certification, compliant with IEC 61508/IEC 61511 safety instrumented systems.
• Flexible Output: Supports both source and sink wiring modes, compatible with various DCS/PLC card requirements.
• Field-Friendly: Ultra-thin 12.5 mm housing, DIN rail mounting, pluggable terminals, maintenance without powering off; front panel labeling for easy circuit identification.
