Pepperl+Fuchs KCD2-STC-Ex1 | HART-Transparent Isolated Barrier for 2-Wire Transmitters, 24V DC
Pepperl+Fuchs KCD2-STC-Ex1 isolated barrier for 2-wire 4-20mA HART transmitters. Ex ia/IIC, 24V DC supply, HART passthrough, DIN rail mount, SIL 2/3.

Product Overview

The Pepperl+Fuchs KCD2-STC-Ex1​ (Order No. KCD2-STC-Ex1) is a single-channel isolated barrier​ from the K-System (KCD2) series, designed to power and isolate a 2-wire (loop-powered) 4-20mA HART transmitter​ installed in a hazardous area (Zone 0/1, Division 1). It provides intrinsic safety (Ex ia) energy limitation​ to the field side and a HART-transparent 4-20mA analog output​ to the safe-area control system. The device is SIL 2/3 capable​ and mounts on a standard 35mm DIN rail.

Key Features

  • HART Protocol Transparency:​ Passes HART FSK digital communication bidirectionally — enables remote configuration, trim, and diagnostics of smart transmitters without removing the barrier.
  • Galvanic 3-Way Isolation:​ Separates hazardous area, safe area, and power supply — protects control system from ground loops and transient surges.
  • Universal 2-Wire Transmitter Support:​ Powers any standard 4-20mA loop-powered HART transmitter (pressure, temperature, flow, level) in Ex ia circuits.
  • Compact DIN Rail Footprint:​ 12.5 mm width — high-density marshalling in system cabinets.

Applications

  • Hazardous Area Analog Loops:​ Connecting 4-20mA HART transmitters (e.g., Endress+Hauser, Yokogawa,) in Zone 1/Division 1​ to DCS/PLC analog input cards.
  • SIS & Process Control:​ SIL 2/3 capable — suitable for safety-related measurement loops where an isolated barrier is required.
  • Fieldbus Migration:​ Retrofit legacy non-smart loops with HART-enabled transmitters — barrier remains in place without rewiring.

Note: For 2-channel​ version see KCD2-STC-Ex1.2​ or KCD2-STC-Ex2​ (dual channel). For non-HART / filtered​ version (blocks digital comms), see KCD2-SD-Ex1.xxx. Always verify Entity Parameters (Uo, Io, Po, Ci, Li) against your transmitter's Ex ia certification before installation.
