Description

Overview

The Pepperl+Fuchs KFD2-UT2-Ex2 is a two-channel isolated barrier and universal temperature converter for hazardous area installations. It converts the signal of a resistance thermometer (RTD), thermocouple, potentiometer or voltage source in the field into a proportional 2-wire current output on the safe side, and can also be configured as a signal splitter with one input and two outputs. Each channel provides intrinsic safety to the field circuits, and the device is certified for installation in Zone 0/1/2 and Division 1/2 applications with SIL 2 capability per IEC/EN 61508 and IEC/EN 61511.

Engineering and Design

The KFD2-UT2-Ex2 accepts RTD types Pt10 to Pt1000 per EN 60751 (plus GOST equivalents), Cu10-100 and Ni100, thermocouple types B, E, J, K, N, R, S, T, L and TXK/TXKH/TXA with internal or external cold junction compensation, potentiometers from 0 to 20 kOhm, and voltage inputs from -100 to 100 mV. Each channel outputs 0-20 mA or 4-20 mA in sink or source mode with a fault signal that follows NAMUR NE43 (downscale 0 or 2 mA, upscale 21.5 mA). Transfer deviation after calibration is typically +/-0.1% of span for Pt100, and the device detects sensor breakage and short-circuit with line fault (LFD) monitoring.

The module is powered from a 24 V DC supply via screw terminals or the P+F Power Rail with a consumption of max 1.53 W per module, and is configured through a programming socket using PACTware. The compact B2 housing measures 20 x 119 x 115 mm (W x H x D) with a mass of approx. 130 g and mounts on a 35 mm DIN rail per EN 60715. Certification includes EU-type examination certificate CESI 04 ATEX 143 with marking II (1)G [Ex ia Ga] IIC, II (1)D [Ex ia Da] IIIC and I (M1) [Ex ia Ma] I, and the removable terminal block K-CJC-** is available for cold junction compensation reference junctions.

About brand

Two specialties define Pepperl+Fuchs, founded in 1945 and headquartered in Mannheim, Germany: industrial sensors for automation, and interface and protection equipment for hazardous areas. Many control cabinets in process plants contain rows of its isolators.

Seven Star LLC lists Pepperl+Fuchs sensors, isolated barriers, power supplies and hazardous-area mobile devices, and supplies them to instrument and automation teams in Oman by exact model designation.

Pepperl+Fuchs product families on this page

On the interface side there are two systems. The K-System mounts on DIN rail and is represented here by the KFD2-UT2-Ex2 universal temperature converter. The H-System plugs into termination boards and is represented by the HiD2030 SMART transmitter power supply with HART. The PS1000-A6-24.20 is a 24 VDC, 20 A power supply for cabinets. Sensors listed include the NJ2-12GK-SN NAMUR inductive sensor, the R101 retro-reflective photoelectric sensor and the R2000 2-D LiDAR scanner. For field staff there are the Tab-Ex 05 DZ1 tablet for Zone 1/21 areas and the Smart-Ex 03 DZ2 smartphone for Zone 2/22 and Division 2 areas.

Where Pepperl+Fuchs equipment is used

Isolated barriers sit between field instruments in Zone 0 or Zone 1 and the DCS or safety system in refineries, gas plants and chemical works. NAMUR sensors report valve position and machine states in classified areas. Photoelectric sensors and LiDAR scanners work in conveying, packaging, warehousing and vehicle guidance. Ex-rated tablets and phones are carried on operator rounds and maintenance jobs.

Ordering Pepperl+Fuchs parts: what we need

Send the complete model designation as printed on the device, including every suffix; a single letter can change the supply voltage or the output type. Add the part number if the label shows one. For barriers, tell us the field device and signal type, the number of channels and whether the safety loop needs a SIL-assessed module. For mobile devices, state the zone or division and the regional radio version.
