Switch Amplifier, KFD2-SRA-EX4

  • 4-channel isolated barrier
  • 24 V DC supply (Power Rail)
  • Dry contact or NAMUR inputs
  • 50 % less wiring, 2:1 technology
  • Relay contact output
  • Line fault detection (LFD)
  • Reversible mode of operation

This isolated barrier is used for intrinsic safety applications. It transfers digital signals (NAMUR sensors/mechanical contacts) from a hazardous area to a safe area.

Each sensor or switch controls one form A normally open relay contact for the safe area load. A special 2:1 wiresaving technology is available on this isolator, reducing field wiring by 50 %.

Switch S1 is used to enable or disable line fault detection of the field circuit. The 2:1 mode is selected with switch S2 while the remaining switches, S3 ... S6, are used for reversing the normal output state of the relays.

A unique collective error messaging feature is available when used with the Power Rail system.
