Product Overview

The KCD2-SCS-2 is a versatile 2-channel signal conditioner from Pepperl+Fuchs' K-System, specifically engineered for applications requiring either analog input or analog output functionality in safe area installations. Each channel can be independently configured as a transmitter power supply (powering 2-wire SMART transmitters) or a current driver (driving SMART I/P converters and positioners).

With a compact 12.5 mm width and 24 V DC power supply (via Power Rail or terminals), this device provides complete galvanic isolation between field and control circuits while supporting bidirectional SMART communication for intelligent field device configuration and diagnostics.

Certifications: SIL 2 DNV Marine CE UL/cULus
Model Number Decoding
Code Segment Meaning
KCD2 K-System, 2-channel housing width (12.5 mm)
SCS SMART Current/Voltage Signal — configurable as transmitter power supply or current driver
-2 2-channel (without Ex certification for safe area use)
The absence of "Ex" in the model number indicates this device is intended for non-hazardous (safe area) installations, distinguishing it from the Ex-version KCD2-SCS-Ex2.
Key Features & Benefits
  • Configurable Per Channel: Each channel can be independently configured via DIP switches as either a transmitter power supply or a current driver
  • Bidirectional SMART Communication: Supports digital communication for SMART devices using current modulation
  • 2-Channel Efficiency: Two independent channels in a single 12.5 mm housing maximizes panel space efficiency
  • SIL 2 Certified: Safety Integrity Level 2 (SC 3) acc. to IEC/EN 61508 for safety-related applications
  • DNV Marine Approval: Certified for marine applications — suitable for shipbuilding and offshore installations
  • High Drive Capability: Provides ≥15 V at 20 mA in transmitter mode; drives loads up to 650 Ω in current driver mode
  • Configurable Control Side Operation: Control side can be operated as current source or current sink
  • Line Fault Detection: Identifies open field circuits for control system monitoring
  • Wide Operating Temperature: Functions reliably from -40°C to +70°C

Function Description

The KCD2-SCS-2 is a configurable signal conditioner for safe area applications. Each of the two channels can operate independently in either mode:

Mode 1: Transmitter Power Supply (Analog Input)
  • Powers 2-wire SMART transmitters
  • Transfers the 4...20 mA measurement signal from the field to the control system
  • Provides bidirectional HART communication for transmitter configuration and diagnostics
  • Minimum available voltage: 15 V at 20 mA ensures reliable transmitter operation
  • Control side can be configured as current source or current sink via DIP switches
Mode 2: Current Driver (Analog Output)
  • Drives SMART I/P converters, valve positioners, and displays
  • Repeats the 4...20 mA control signal from the PLC/DCS to the field device
  • Supports bidirectional HART communication for positioner configuration and feedback
  • Drives loads up to 650 Ω with ≥13 V at 20 mA
  • Line fault detection identifies open field circuits for control system monitoring
