PEPPERL + FUCHS KFD2-SL2-EX1.LK / KFD2SL2EX1LK RELAY PART NO 200542

Product Description

The Pepperl+Fuchs KFD2-SL2-EX1.LK (Part No. 200542) is an intrinsic safety isolated switch amplifier and relay module, part of Pepperl+Fuchs' renowned K-System series. This device is designed for reliable signal transmission between hazardous and safe areas, ensuring intrinsic safety in process automation systems.

Key Features:

1. Functionality:

   • An isolated switch amplifier that transfers signals from switches or proximity sensors in hazardous areas to control systems in safe zones.
   • Converts input signals into relay output signals for safe zone operation.
   • Ensures intrinsic safety, making it suitable for exp losive or flammable environments.

2. Inputs:

   • Accepts signals from NAMUR sensors or mechanical contacts in the hazardous area.
   • NAMUR Standard: Detects both open and closed states of a sensor with low power consumption.

3. Outputs:

   • Features a relay output that drives actuators or interfaces with PLCs and other control systems in the safe area.
   • Relay provides electrical isolation and high reliability for control signals.

4. Safety Features:

   • Intrinsic Safety Compliance: Certified for use in Zone 0, Zone 1, and Zone 2 hazardous areas.
   • Protects against overvoltage, overcurrent, and other electrical faults.
   • Galvanic isolation ensures signal integrity and protects equipment from ground loops.

5. Specifications:

   • Power Supply: Typically operates at 24V DC.
   • Contact Rating: Relay contacts can handle small loads (typically up to 2A).
   • Input Signal: NAMUR or dry contact signal.
   • Mounting: DIN-rail mountable for easy integration into standard control panels.

6. Environmental Suitability:

   • Designed for harsh industrial environments, resistant to temperature fluctuations, vibration, and moisture.

7. Certifications:

   • ATEX, IECEx, and other global certifications for use in hazardous locations.
   • Meets stringent industry standards for intrinsic safety and reliability.

Applications:

• Oil and Gas: Monitoring and control in refineries and offshore platforms.
• Chemical Plants: Ensuring safe signal transmission in reactive or expl osive environments.
