Realize SIL 3 with New H-System Solenoid Drivers

Solenoid drivers can be used in applications up to SIL 3
Solenoid drivers can be used in applications up to SIL 3

Four new H-System solenoid drivers are now available, allowing you to realize applications up to SIL 3. Choose between our one-channel, 12.5 mm small HiC2873 and HiC2877 modules, or the two-channel, 18 mm width HiD2872 and HiD2876 isolated barriers. All four modules can be mounted on universal or DCS-specific termination boards.

Features at a glance

  • High SIL level up to SIL 3
  • Line fault detection of field loops and control cables 
  • Single Loop Integrity: reduced space requirements in single-channel applications due to 12.5 mm HiC housings
  • High packing density (9 mm per channel) when using dual-channel isolated barriers in HiD housing
  • Output—technical details
    • HiC2877, HiD2872: 40 mA, 11.2 V
    • HiC2873, HiD2876: 40 mA, 12 V
  • Selectable test pulse immunity for test pulses coming from the control system
