Product Overview

The KCD2-SCS-Ex2 is a versatile 2-channel isolated barrier from Pepperl+Fuchs' K-System, specifically engineered for intrinsic safety applications requiring either analog input or analog output functionality. 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.

Certified for SIL 2 (SC 3) acc. to IEC/EN 61508 and approved for hazardous area installation with [Ex ia Ga] IIC certification, the KCD2-SCS-Ex2 is the ideal solution for analog signal transfer in safety-related and explosive atmosphere applications.

Function Description

The KCD2-SCS-Ex2 is a configurable isolated barrier for intrinsic safety applications. Each of the two channels can operate independently in either mode:

Mode 1: Transmitter Power Supply (Analog Input)
  • Powers 2-wire SMART transmitters located in hazardous areas
  • 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 in hazardous areas
  • 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

Unique Application Capability: Positioners ensure that the actuator is brought into a position specified by the control system. They are often equipped with analog position indicators whose feedback confirms that the position specification has been performed. Previously, a separate isolator module was required for the input and output signal. With the KCD2-SCS-Ex2, these two functions can be used in one device for the first time -- positioner control on one channel (AO) and position monitoring (AI) on the second channel.

Applications

The KCD2-SCS-Ex2 is specifically designed for analog signal transfer in hazardous area installations:

Oil & Gas Powering pressure/temperature transmitters on offshore platforms; driving I/P converters for pipeline control valves in Zone 1 areas
Chemical Processing Isolated analog input for reactor monitoring; analog output for chemical dosing valve positioning in explosive atmospheres
Pharmaceutical SIL 2 certified signal transfer for safety-related batch control; solvent handling equipment with Ex ia protection
Power Generation Transmitter power supply for gas turbine monitoring; current driver for boiler feedwater control valves
Valve Positioner Applications Combined positioner control (AO) and position feedback monitoring (AI) in a single device -- eliminates need for separate isolator modules
Typical Field Devices Connected
  • 2-wire SMART pressure, temperature, level, flow, and pH transmitters (Analog Input mode)
  • SMART I/P converters for pneumatic valve positioning (Analog Output mode)
  • SMART valve positioners with HART communication and analog position feedback (AI + AO combined)
  • Field-mounted displays with 4...20 mA input (Analog Output mode)
Why Choose the KCD2-SCS-Ex2?
Industry-First 2-Channel AI/AO Design -- The KCD2-SCS-Ex2 is the first 2-channel, dual-function AI/AO intrinsic safety barrier in a 12.5 mm housing. This unique capability allows positioner control and position monitoring in a single device -- previously requiring two separate isolator modules.
Complete Intrinsic Safety Package -- Certified with [Ex ia Ga] IIC for Zone 0, 1, and 2 hazardous areas, the device provides the highest level of intrinsic safety protection for gas groups IIC (hydrogen, acetylene), IIB, and IIA.
SIL 2 Certified for Safety Applications -- Certified acc. to IEC/EN 61508 with Systematic Capability SC 3 (TÜV Rheinland), the KCD2-SCS-Ex2 is suitable for use in safety instrumented systems (SIS) up to SIL 2.
Configurable Control Side Operation -- For analog input signals, the control side can be operated as either a current source or current sink via front-panel DIP switches, providing compatibility with any control system architecture.
Bidirectional SMART Communication -- Full HART transparency allows digital configuration, calibration, and diagnostics of SMART field devices directly through the isolation barrier -- no additional hardware required.
Space-Saving Design -- At just 12.5 mm width, the KCD2-SCS-Ex2 provides two complete analog signal channels in a compact footprint, maximizing DIN rail density.
High Drive Capability -- The current driver mode delivers ≥13 V at 20 mA into 650 Ω loads, providing sufficient power for demanding positioners and long cable runs.
Proven Pepperl+Fuchs K-System -- The K-System is the industry standard for signal conditioning and isolation, trusted globally for reliability, quality, and long service life.
