KSD2-CO-S-Ex PEPPERL FUCHS Isolator

Description KSD2-CO-S-Ex PEPPERL FUCHS Isolator Product Dimensions： Product Description (Detailed Explanation) The KSD2-CO-S-Ex acts as an isolated barrier that transfers a 4 mA – 20 mA signal from a control system (PLC/DCS) to a field device in an intrinsically safe (Ex) circuit. The “S” in the model name indicates SMART capability, meaning it supports bidirectional communication using the HART protocol. This allows digital diagnostic data and configuration parameters to be superimposed on the analog signal. As part of the K-System/RPI line, it mounts on a Power Rail, which simplifies wiring by providing power and internal communication through the rail itself. The module provides galvanic isolation between the field circuit, the control circuit, and the power supply, ensuring high signal integrity and safety. Product Parameters (Technical Specifications) Parameter Category Specification Signal Type Analog Output (SMART/HART) Current Range 4 mA to 20 mA Safety Rating Intrinsically Safe (Ex ia) Hazardous Area Zone Can connect to Zone 0, 1, 2; Class I, II, III, Div. 1/2 Internal Resistance $\ge 250 \Omega$ (HART compatible) Load Max. 650 $\Omega$ at 20 mA Supply Voltage 24V DC (via Power Rail) Isolation 3-way isolation (Power / Input / Output) Response Time $\le 100$ ms Connection Removable terminals (blue for Ex-side) Product Advantages (Key Benefits) Intrinsically Safe: Certified for the highest protection levels, allowing for the safe operation of field devices in explosive atmospheres. HART Transparency: Supports full HART communication, enabling remote valve calibration, status monitoring, and asset management from the control room. Compact Design: Part of a high-density system that saves significant space in the control cabinet compared to traditional barriers. Redundancy & Reliability: Features internal monitoring and is designed for long-term stability in continuous-process industries. Reduced Wiring: The Power Rail integration eliminates the need for individual power daisy-chaining, reducing the risk of wiring errors. Precautions (Important Notes) Hazardous Area Separation: Always ensure that the blue intrinsically safe (Ex) terminals are physically separated from the non-intrinsically safe (control/power) wiring to prevent energy leakage. Load Limits: Verify that the total loop resistance (actuator cable) does not exceed the 650 $\Omega$ limit; otherwise, the module may not be able to drive the full 20 mA signal. Configuration: Use the Pepperl Fuchs PACTware software or a compatible DTM for initial module configuration and detailed diagnostics. Mounting Environment: Ensure the module is installed in an IP54 or higher rated enclosure if the surrounding environment is subject to dust or moisture. Product Applications (Typical Use Cases) Chemical Plants: Controlling the position of hazardous-area valves used in volatile liquid processing. Oil & Gas Refineries: Driving I/P converters that manage pneumatic actuators on large-scale pipeline systems. Pharmaceutical Batching: Precise control of dosing valves where explosive dust or vapors may be present. Offshore Platforms: Managing safety-critical control elements in confined spaces where space-saving high-density modules are required. Power Generation: Regulating fuel flow control valves in turbine systems located in classified hazardous zones.
