SMART Current Driver KCD2-SCD-Ex1.ES

  • 1-channel isolated barrier
  • 24 V DC supply (Power Rail)
  • Current output up to 650 Ω load

  • Line fault detection (LFD)
  • Housing width 12.5 mm
  • Up to SIL 3 acc. to IEC/EN 61508

This isolated barrier is used for intrinsic safety applications. The device repeats the input signal from a control system to drive HART I/P converters, electrical valves, and positioners located in a hazardous area. Digital signals are superimposed on the analog values at the field side or control side and are transferred bi-directionally. The current is transferred via a DC/DC converter and repeated at the output terminals. An open or short field circuit presents a high impedance to the control side to allow alarm conditions to be monitored by the control system. Test sockets for the connection of HART communicators are integrated into the terminals of the device. A fault is signalized by LEDs and a separate collective error message output.
