Product Overview

The KFA5-SR2-EX1.W is a 1-channel isolated Switch Amplifier for intrinsic safety applications. It transfers digital signals (NAMUR sensors/mechanical contacts) from a hazardous area to a safe area. The proximity sensor or switch controls a form C changeover relay contact for the safe area load. The barrier output changes state when the input signal changes state. The normal output state can be reversed using switch S1. Switch S3 is used to enable or disable line fault detection of the field circuit. During an error condition, the relay reverts to its de-energized state and the LEDs indicate the fault according to NAMUR NE44.
  • 115VAC Supply voltage
  • Dry contact or NAMUR inputs
  • Relay contact output
  • Line fault detection (LFD)
  • Reversible mode of operation
  • Up to SIL2 according to IEC 61508/IEC 61511
