PEPPERL+FUCHS KSD2-CO-S-Ex Isolator

Product Dimensions：

The Pepperl+Fuchs KSD2-CO-S-Ex is a high-performance Analog HART Output Driver/Repeater module. It belongs to the K-System family and is specifically designed as an isolated barrier to provide intrinsically safe signals to actuators, positioners, and I/P converters located in hazardous areas.

Product Detailed Description

The KSD2-CO-S-Ex is a 1-channel module that transmits a 0/4 mA to 20 mA current signal from a control system (Safe Area) to a field device (Hazardous Area). It is unique because it supports bidirectional HART communication, allowing digital diagnostic and configuration data to pass through the analog signal without interference.

Technical Parameters

Product Advantages

• HART Transparency: Supports the full HART protocol, enabling remote calibration and monitoring of smart positioners directly from the control room.
• Integrated Diagnostics: Features Lead Breakage (LB) and Short Circuit (SC) monitoring. If a fault is detected in the field wiring, the module alerts the system via the Power Rail bus.
• Compact Design: At only 20 mm wide, it provides high-density signal conditioning, saving valuable cabinet space.
• Galvanic Isolation: Provides safe electrical isolation between the hazardous field circuit and the non-intrinsically safe control side, protecting expensive PLC hardware.
• Power Rail Integration: Reduces wiring complexity by drawing power and transmitting diagnostic data through the DIN rail bus system.

Important Considerations (Precautions)

• Hazardous Area Standards: The module itself must be installed in a Safe Area or Zone 2, but it is designed to connect to devices in Zone 0, 1, or 2.
• Air Quality/Environment: Rated IP20. It must be installed in a clean, dry enclosure (IP54 minimum recommended if the environment is harsh or dusty).
• Terminal Wiring: Use only one conductor per terminal. If using stranded wire, ensure wire-end ferrules are crimped to prevent shorts.
• Load Limits: Ensure the connected load is between 30 \Omega and 750 \Omega. Operating outside this range may trigger a fault signal or prevent the field device from functioning correctly.

Product Applications

The KSD2-CO-S-Ex is essential for high-risk process industries:

• Valve Positioning: Controlling intrinsically safe pneumatic positioners in chemical and gas plants.
• I/P Converters: Driving current-to-pressure converters that operate heavy-duty control valves.
• Smart Actuators: Interfacing with any field device that requires a 4-20 mA setpoint and uses HART for advanced diagnostics.
• Remote Monitoring: Used in “Remote Process Interface” (RPI) systems where many signals are consolidated onto a single digital bus.
