- Supports multiple input signal types, including thermocouples (e.g., Type K, Type J), resistance temperature detectors (RTDs, e.g., Pt100), 4-20mA current signals, and mV voltage signals.
- Outputs standard signals (4-20mA or 1-5V) that can meet the input requirements of control systems such as DCS and PLC.
- Equipped with signal conversion function: for example, linearizing the mV signal of thermocouples into 4-20mA current signals, or converting RTD resistance values into standard voltages.
- Certified by ATEX (EU) and NEPSI (China), suitable for intrinsically safe circuits in hazardous areas (e.g., chemical, petrochemical industries).
- Meets the requirements of SIL2 safety level and can be used in safety-related systems.
- Integrates on-site line fault detection function, which can monitor abnormalities such as open circuits and short circuits, and transmit a unified alarm signal to the power module through the power rail.
- Equipped with LED indicators on the barrier for intuitive display of line fault status.
- Fully compatible with intelligent communication protocols such as HART and Brain, supporting the communication needs of two-wire and four-wire intelligent transmitters.
- Enables debugging of HART instruments on the system side via a handheld communicator, and is compatible with application scenarios of non-intelligent instruments.
- Supply Voltage: 19-30VDC, power consumption approximately 0.35W (at 24V/1mA).
- Output Load Capacity: For 4-20mA signals, the maximum load resistance depends on the supply voltage (e.g., approximately 600Ω at 24V).
- Accuracy Class: Typical value ±0.1% FS, ensuring the accuracy of signal conversion.
- Signal conversion response time ≤100ms, meeting the requirements of industrial real-time control.
- Operating Temperature Range: -25℃ to +60℃, adapting to harsh industrial environments.
- Protection Class: IP20, suitable for cabinet mounting.
- Adopts DIN rail mounting method, supporting 35mm standard rails for easy installation and disassembly.
- Plug-in terminals distinguish between the field side and system side (marked with different colors) to avoid wiring errors.
- Supports rail power supply (centralized power supply via power rail), simplifying the complexity of multi-module power distribution and enabling redundant power supply design.
- Can be directly plugged with P-LB series surge protectors, saving cabinet space and enhancing anti-interference capability.
- Converts on-site thermocouple/RTD signals into standard signals for reactor temperature control, while meeting the intrinsically safe explosion-proof requirements of hazardous areas.
- Monitors the drive signal of control valves and prevents valve out-of-control through line fault detection.
- Transmits temperature sensor signals to the DCS system in power generation equipment to realize unit operation status monitoring.
- Supports hygienic installation and is suitable for isolation and transmission of temperature and pressure signals in cleanroom environments.
- KFD0: KF series safety barrier; CS: signal conversion function; 1.50: specific specification code (e.g., input range, accuracy class).
- Optional cold-junction compensator (e.g., K-CJC) for thermocouple applications to offset the impact of ambient temperature changes on measurements.
- Supports configuration software (e.g., PW2-ADP1-USB) for parameter configuration and debugging.
- Manufacturer: Pepperl+Fuchs (Germany), a world-leading supplier of industrial sensors and safety barriers.
- Chinese Suppliers: Pepperl+Fuchs Shanghai, Xiamen KuanTu Automation, etc., providing spot sales and technical consulting.
- Technical Documents: Product manuals, detailed wiring diagrams, certification certificates, and application cases can be downloaded from the Pepperl+Fuchs official website.
- Plug-in terminals of different colors must be used for the field side and system side to avoid confusion.
- Thermocouple inputs must be correctly connected to the cold-junction compensator to ensure measurement accuracy.
- If the LED indicator alarms, check whether the on-site wiring connections are loose or short-circuited; if necessary, read HART diagnostic information via a handheld communicator.
- Installation must comply with the installation specifications of ATEX and NEPSI certifications, ensuring that grounding and power distribution meet standards.
With its high reliability, multi-signal compatibility, and intrinsically safe explosion-proof characteristics, the KFD0-CS-1.50 has become a core component for signal isolation and processing in industrial automation, widely used in complex industrial scenarios where hazardous energy needs to be strictly controlled.
