Product Description

Product Description

Product Overview

The Pepperl+Fuchs KCD2-SCD-EX1 Safety Barrier is a high-performance intrinsic safety (IS) barrier designed for use in hazardous industrial environments. It serves as a critical interface between field devices located in explosive atmospheres (Zone 0/20, 1/21, or 2/22) and control systems in safe areas. This device ensures the safe transmission of signals by limiting electrical energy to non-incendive levels, effectively preventing sparks or thermal effects that could ignite flammable gases, dust, or vapors. The KCD2-SCD-EX1 is compatible with a wide range of field instruments, including sensors, transmitters, and actuators, and supports both analog (4–20 mA) and discrete (NAMUR) signal types. Its robust construction and compliance with international standards make it a reliable choice for oil and gas, chemical, pharmaceutical, and other process industries where safety and precision are paramount.

Advanced Design and Versatility

A key advantage of the KCD2-SCD-EX1 lies in its compact, DIN-rail-mounted design, which optimizes space in control cabinets while simplifying installation. The barrier features galvanic isolation between input and output circuits, eliminating ground loops and ensuring signal integrity in noisy environments. With a wide operating voltage range (18–32 V DC) and a high protection rating (IP20), it performs reliably under demanding conditions. Its universal compatibility extends to both passive and active field devices, offering flexibility for diverse applications. Additionally, the device supports HART communication, enabling seamless integration with modern digital protocols for advanced diagnostics and real-time data transmission. These features reduce system complexity and enhance operational efficiency across industrial networks.

Certified Safety and Compliance

The KCD2-SCD-EX1 meets stringent global safety standards, including ATEX, IECEx, UL, and CSA certifications, ensuring compliance in virtually any region. Its intrinsic safety concept adheres to IEC/EN 60079-11 and IEC/EN 60079-14, guaranteeing protection for equipment in explosive atmospheres. The barrier's redundant circuit design and fault-tolerant architecture minimize downtime by preventing single-point failures from disrupting critical processes. It also features a high dielectric strength (2.3 kV) and low power dissipation, reducing heat generation and energy consumption. These attributes not only enhance safety but also lower lifecycle costs by extending equipment longevity and minimizing maintenance requirements.

Operational Reliability and Cost Efficiency

Operational Reliability and Cost Efficiency

Pepperl+Fuchs' KCD2-SCD-EX1 excels in delivering long-term reliability through its ruggedized components and self-monitoring capabilities. The device operates across a broad temperature range (-40°C to +80°C), making it suitable for extreme climates. Its plug-and-play design eliminates the need for complex calibration, reducing commissioning time and labor costs. 

Furthermore, the barrier's modular architecture allows for easy expansion or reconfiguration of control systems, supporting scalability as operational needs evolve. By combining fail-safe performance with low total cost of ownership, the KCD2-SCD-EX1 provides a future-proof solution for industries prioritizing safety, compliance, and operational continuity in hazardous areas.

Specification

Step	Procedure	Details
