Pepperl+Fuchs KFA6-SR2-Ex1.W NAMUR Digital Input Switch Amplifier

1-channel isolated barrier for intrinsically safe NAMUR sensor and dry contact inputs

Overview

The Pepperl+Fuchs KFA6-SR2-Ex1.W is a 1-channel isolated barrier used for intrinsic safety applications, transferring digital signals from a hazardous area to a safe area. It supports NAMUR sensor inputs per EN 60947-5-6, or mechanical/dry contact inputs, and features line fault detection (LFD) for monitoring the control circuit for lead breakage, along with a reversible mode of operation. The proximity sensor or switch controls a form C changeover relay contact for the safe area load, and during an error condition, the relay reverts to its de-energized state with LED fault indication according to NAMUR NE44. Operating on a 230V AC supply, this switch amplifier is designed as a safety barrier for connecting hazardous-area sensors to standard control systems.

Key Features

  • Intrinsically safe signal isolation: Transfers digital signals safely from a hazardous (Ex) area to a standard control system in a safe area.
  • Dual input compatibility: Accepts both NAMUR sensor inputs (per EN 60947-5-6) and dry mechanical contacts.
  • Line fault detection (LFD): Monitors the field circuit for wire breakage or short-circuit conditions.
  • Reversible operation mode: Output state can be reversed via onboard switches to suit different application logic.
  • Relay contact output: Form C changeover relay output for driving safe-area control loads.
  • 230V AC supply: Standard mains-compatible power supply for straightforward integration into control panels.
