Pepperl+Fuchs HiC2853R1 Relay Output Switch Amplifier (Part No.: HiC2853R1)

Pepperl+Fuchs HiC2853R1 Relay Output Switch Amplifier

 (Part No.: HiC2853R1)

The Pepperl+Fuchs HiC2853R1 is a specialized switch amplifier designed to provide a robust and reliable interface between a single intrinsically safe (IS) field sensor in a hazardous area and a control system in a safe area. This unit features a relay output, making it ideal for applications requiring electrical isolation or the switching of higher loads directly from the amplifier output.

Key Features

• Relay Output Configuration: The "R1" suffix indicates a single relay output with a Form A (SPST, normally open) or Form C (SPDT) contact. This provides galvanic isolation between the input and output circuits and allows switching of AC/DC loads, such as contactors, solenoids, or indicator lamps, directly.

• Intrinsic Safety (IS) Input: The input side is certified for intrinsic safety, allowing direct connection to sensors (e.g., limit switches, proximity sensors, NAMUR sensors) located in Zone 0/1/20/21 hazardous areas without additional protection.

• Single-Channel Design: Provides a dedicated, high-integrity interface for a single critical field device. This is often preferred for safety interlocks or critical monitoring points where channel independence is paramount.

• Clear Diagnostic Indication: Features LED status indicators for power, input signal state, and output relay status, enabling immediate visual troubleshooting at the device.

• Robust Industrial Construction: Housed in a compact module designed for 35mm DIN rail mounting. Features screw terminals for secure and reliable electrical connections suitable for industrial environments.

• Wide Sensor Compatibility: Compatible with common two-wire and three-wire DC field sensors, including energy-limited NAMUR-type proximity sensors and mechanical contacts.
  
  

  

Applications

• Emergency Stop (E-Stop) Circuits: Interfacing a hazardous-area emergency stop button directly to a safety relay or controller via an isolated relay output.

• Critical Valve Position Feedback: Monitoring the open/closed status of a valve actuator in a hazardous area and providing a robust relay signal to the control system.

• High-Level/Low-Level Alarm: Connecting a single-point level switch in a tank and using the relay to activate an alarm horn, strobe light, or pump shutdown.

• Flame Detection or Gas Detection: Interfacing a single detector head and providing a relay output to trigger ventilation systems or master alarms.

• Machine Guarding: Monitoring a safety gate switch and providing an isolated relay signal to a safety controller to enable machine operation.

Why Choose the Pepperl+Fuchs HiC2853R1?

Pepperl+Fuchs HiC2853R1 | Switch Amplifier | Relay Output | DIN Rail | Intrinsic Safety

• Direct Load Switching: The relay output can switch auxiliary loads directly, eliminating the need for an additional interposing relay in many cases.

• Electrical Isolation: The relay provides complete galvanic isolation between the sensitive IS field circuit and the load circuit, enhancing system robustness and safety.

• High Reliability for Critical Signals: Single-channel design is often used for critical signals where failure of one channel should not affect others.

• Simple Integration: Clear terminal design and status LEDs make installation and troubleshooting straightforward.

• Trusted Safety Component: Manufactured by Pepperl+Fuchs, a leader in intrinsic safety technology.
