Pepperl+Fuchs HiC5861 Relay Module (Part No.: HiC5861)

Pepperl+Fuchs HiC5861 Relay Module (Part No.: HiC5861)

The Pepperl+Fuchs HiC5861 is a versatile 4-channel relay module designed as a key interface component for control systems in hazardous areas. This device performs essential signal conversion and isolation, enabling safe and reliable switching between intrinsically safe (IS) circuits in potentially explosive atmospheres and higher-power circuits in safe areas.

Key Features

• Quadruple Relay Configuration: Integrates four independent electromechanical relays, each with a changeover (SPDT or Form C) contact, providing flexibility for multiple switching tasks in a single, compact unit.

• Intrinsic Safety (IS) Compatibility: The input side of the module is designed to be used within intrinsically safe circuits, allowing it to be safely installed and operated in Zone 1/21 hazardous areas or as part of an IS interface assembly.

• Signal Conversion & Amplification: Primarily functions to convert low-power, intrinsically safe control signals (e.g., from an IS logic solver or switch amplifier) into robust relay contact outputs capable of switching higher-power loads like solenoids, contactors, indicator lights, or alarm devices in the safe area or within the IS system.

• Galvanic Isolation: The relay contacts provide complete electrical isolation between the control (coil) side and the load (contact) side. This is crucial for preventing ground loops, noise interference, and for meeting safety separation requirements.

• Modular DIN Rail Design: Compact form factor for easy installation on standard 35mm DIN rails within control cabinets or marshalling panels. Features pluggable terminal blocks for simplified wiring and maintenance.

• Individual Channel Status: Each of the four channels is typically equipped with LED indicators to show the status of the relay coil (energized/de-energized), providing immediate visual diagnostics.

Applications

• Logic Solver Output Interface: Converting the low-current outputs of an IS safety controller or logic solver into relay contacts to drive final elements like valves or motors.

• Alarm & Annunciation: Switching audible alarms (horns) and visual signals (strobes, beacon lights) based on signals from IS sensors.

• Motor/Starter Control: Providing isolated relay commands to start/stop motors or control motor starter coils based on IS logic.

• Multi-Point Switching: Replacing multiple single-channel devices in applications requiring several isolated switching points from an IS system.

Why Choose the Pepperl+Fuchs HiC5861?

Pepperl+Fuchs HiC5861 | Relay Module | Intrinsic Safety | DIN Rail | Zone 1/21

• Space and Cost Efficiency: Four relays in one module reduce panel space, wiring, and component count compared to using four individual relay units.

• Enhanced System Integrity: Provides reliable galvanic isolation, protecting sensitive IS circuits from disturbances on the load side.

• Flexible Control: The changeover contacts allow wiring in either normally open (NO) or normally closed (NC) configuration for each channel.

• Simplified Troubleshooting: Per-channel LED indication allows for quick identification of which specific relay is active or has failed.

• Proven Reliability: Manufactured by Pepperl+Fuchs, a global leader in industrial interface and safety technology.
