Switch Amplifier KFD2-ST3-Ex2

  • 2-channel isolated barrier
  • 24 V DC supply (Power Rail)
  • Dry contact or NAMUR inputs
  • Active transistor output
  • Line fault detection (LFD)
  • Reversible mode of operation
  • Up to SIL 2 (SC 3) acc. to IEC/EN 61508

Details: KFD2-ST3-Ex2


This isolated barrier is used for intrinsic safety applications.

The device transfers digital signals (NAMUR sensors or dry contacts) from a hazardous area to a safe area.

Each input controls an active transistor output.

Via switches the mode of operation can be reversed and the line fault detection can be switched off.

A fault is signalized by LEDs acc. to NAMUR NE44 and a separate collective error message output.
