Pepperl+Fuchs HiC2821 Switch Amplifier (Part No.: HiC2821)

Pepperl+Fuchs HiC2821 Switch Amplifier (Part No.: HiC2821)

The Pepperl+Fuchs HiC2821 is an 8-channel switch amplifier designed to interface between intrinsically safe (IS) field devices in hazardous areas and control systems in safe areas. This versatile device converts signals from IS sensors (like limit switches, proximity sensors) into amplified, safe-area signals for PLCs, DCS, or other control equipment, providing reliable monitoring and control in potentially explosive atmospheres.

Key Features

• 8-Channel Interface: Provides eight independent channels in a single compact module, allowing connection of multiple field sensors, maximizing space efficiency in control cabinets.

• Intrinsic Safety (IS) Inputs: Each input channel is certified for intrinsic safety (ATEX/IECEx), allowing direct connection to sensors located in Zone 0/1/20/21 hazardous areas without additional isolators.

• Flexible Output Configuration: Each channel typically offers configurable relay or transistor outputs (sourcing or sinking), providing versatility to interface with a wide range of safe-area control system inputs (e.g., PLC digital input cards).

• Channel Independence & Diagnostics: Features individual LED status indicators for each channel, showing power, input state, and output state, enabling quick troubleshooting and pinpointing of field device issues.

• Compact DIN Rail Design: 35mm DIN rail mounting with pluggable terminal blocks or screw terminals for easy installation, wiring, and maintenance.

• Wide Sensor Compatibility: Compatible with a broad range of two-wire and three-wire DC sensors (NAMUR, mechanical contacts) commonly used in process and factory automation.

Applications

• Tank Farm Monitoring: Interface for level switches, pressure switches, and temperature switches in hazardous storage areas.

• Chemical & Pharmaceutical Plants: Connecting limit switches on valves, door interlocks, and flow sensors in explosive atmospheres.

• Oil & Gas Facilities: Monitoring pump status, valve position, and safety interlocks on offshore platforms and refineries.

• Bulk Material Handling: Interface for belt misalignment switches, plugged chute detectors, and bin level switches in areas with combustible dust.

• Packaging & Food Processing: Connecting safety gates, guard interlocks, and product presence sensors in washdown or hazardous areas.
