KSD2-CO-S-Ex.H PEPPERL FUCHS Analog HART Output Driver

Description KSD2-CO-S-Ex.H PEPPERL FUCHS Analog HART Output Driver Product Dimensions： Product Description (Detailed Explanation) The KSD2-CO-S-Ex.H acts as an isolated barrier and signal converter. It receives a digital signal from the RPI system bus and converts it into a high-precision 4…20 mA analog output to control field equipment such as control valves, I/P converters, or positioners located in Zone 0, 1, or 2. The module is “SMART” because it is transparent to HART communication. It allows digital HART signals to be superimposed on the analog current loop, enabling the control system (DCS/PLC) to perform remote configuration, calibration, and diagnostics of the field instrument. The module also features comprehensive line fault detection, identifying open or short circuits in the field wiring. Product Parameters (Technical Specifications) Parameter Category Specification Safety Type Intrinsically Safe [Ex ia Ga] IIC (Hazardous Area) Output Signal 4…20 mA DC (Source) Load Impedance Max. 700 Ω (at 20 mA) HART Transparency Bidirectional (Frequency Shift Keying / FSK) Accuracy <0.1% of full scale Response Time <100 ms (10% to 90% of step change) Internal Power 24V DC (via Power Rail or Bus) Line Monitoring Open circuit and short circuit detection Isolation Galvanic isolation (Input / Output / Power) Mounting 35mm DIN Rail (RPI System specific) Product Advantages (Key Benefits) Intrinsically Safe Output: Certified for the highest safety standards, allowing direct connection to devices in explosive atmospheres without additional barriers. HART Communication Support: Allows for “Pass-Through” of HART commands, enabling centralized management of SMART field devices (e.g., via AMS or PACTware). High Reliability & Precision: Low temperature drift and high accuracy ensure precise control of critical process valves. Integrated Diagnostics: Automatically detects and reports field-side wiring faults, significantly reducing troubleshooting time during plant outages. Hot-Swappable: The module can be replaced during operation without disturbing the system bus or other modules in the rack. Precautions (Important Notes) Entity Parameters: When connecting to a field device, always verify that the entity parameters (Uo​,Io​,Po​) of the KSD2-CO-S-Ex.H are compatible with the field device (Ui​,Ii​,Pi​) to maintain intrinsic safety. Grounding: Ensure that the DIN rail or Power Rail is properly grounded according to the explosion protection regulations (IEC/EN 60079-14). Load Limits: Do not exceed the maximum load of 700 Ω. Excessive resistance will cause the current loop to saturate and the control valve to behave unpredictably. Signal Interference: Ensure that field wiring is kept separate from high-voltage cables to prevent electromagnetic interference (EMI) from degrading the HART digital signal. Product Applications (Typical Use Cases) Petrochemical Plants: Driving pneumatic control valves in explosive refining units. Oil & Gas Offshore Platforms: Controlling actuator positioning on wellhead manifolds where space and safety are critical. Chemical Processing: Managing variable-speed dosing pumps via I/P converters in hazardous batch reactors. Pharmaceutical Manufacturing: Precision control of sterile valves in environments involving flammable solvents. Wastewater Treatment: Operating methane gas flare valves in digestion tanks.
