The KFD2-UT2-EX1 from Pepperl+Fuchs is a versatile 1-channel isolated barrier tailored for precise temperature signal conversion. It handles thermocouple, RTD, potentiometer, and voltage inputs with ease. This unit delivers a standard current output of 0/4 mA to 20 mA, selectable between sink or source mode. Configuration is straightforward using PACTware software. Additionally, it includes line fault detection (LFD) and sensor burnout monitoring for enhanced system reliability. Safety is a key focus, as this model meets SIL2 requirements per IEC 61508. Its compact design, measuring just 2 cm wide, saves valuable cabinet space.
This device operates on a rated voltage of 20 to 30 V DC, typically powered via a 24 V DC supply rail. The primary output is a 4-20 mA analog signal, which is widely used in industrial control loops. For input flexibility, the KFD2-UT2-EX1 accepts various sensor types. These include thermocouples (types B, E, J, K, N, R, S, T), 2-, 3-, or 4-wire RTDs (Pt100, Pt500, Pt1000), potentiometers, and standard voltage signals (0-100 mV or 0-10 V). The output can be configured for either sink or source mode, making it adaptable to different PLC or DCS input requirements. Configuration and diagnostics are managed through the PACTware software interface, which provides a user-friendly environment for setting parameters. Furthermore, the built-in line fault detection (LFD) continuously monitors the field wiring for breaks or shorts, while sensor burnout detection alerts the control system to sensor failures.
Safety is paramount in process automation, and the KFD2-UT2-EX1 does not disappoint. It is certified for functional safety up to SIL2 according to IEC 61508. This qualification makes it a reliable choice for safety-instrumented functions. The device also features Ex-Input explosion protection, which allows it to interface with sensors located in hazardous zones. Consequently, it ensures safe signal transmission between the field and the control room without compromising protection levels.
This universal temperature converter is built for industrial environments. Its dimensions are 2 cm in width, 11.9 cm in height, and 11.5 cm in depth, which conforms to the standard K-System housing. The unit weighs approximately 0.13 kg, making it lightweight for DIN-rail mounting. The operating temperature range is typically -20°C to +60°C, ensuring reliable performance in most plant conditions. Storage temperature extends from -25°C to +85°C. The housing is made of robust, flame-retardant polyamide, offering good resistance to common chemicals and moisture. Moreover, the terminals accept wire sizes up to 2.5 mm², facilitating easy and secure connections.
Mounting the KFD2-UT2-EX1 is simple and follows standard industry practices. First, snap the device onto a 35 mm DIN rail according to EN 60715. Ensure adequate spacing between units for proper ventilation, although side-by-side mounting is typically acceptable. Next, connect the power supply to terminals 1 and 2, observing the correct polarity for the 24 V DC feed. The input sensor wires are connected to terminals 3 through 8, depending on the sensor type. For example, a 3-wire RTD connects to terminals 4, 5, and 6. The output signal is available at terminals 11 (+) and 12 (-). Furthermore, always use shielded cables for sensor connections to minimize electrical noise interference. Finally, configure the device settings using PACTware before commissioning. Remember, the configuration software allows you to set the input type, output range, and fault detection thresholds.
Your shipment will include one KFD2-UT2-EX1 device. It comes securely packed with a product label and the necessary terminal plugs for wiring. The package also contains a quick-start guide that illustrates basic installation steps. However, a detailed instruction manual is available for download from the manufacturer's website. For delivery, we utilize reliable global couriers such as Fedex, UPS, and DHL. Consequently, you can expect fast and trackable shipping directly to your facility. Please note that the packaging excludes any certificates or warranty documents, as these are handled separately.
1. What input sensor types does the KFD2-UT2-EX1 support?
It supports thermocouples (B, E, J, K, N, R, S, T), 2/3/4-wire RTDs (Pt100, Pt500, Pt1000), potentiometers, and mV/V voltage signals. This broad compatibility makes it a truly universal converter.
