Equipment and systems covered by this certificate are as follows:

The Galvanically Isolated Barrier type HiC Series is a group of associated apparatus suitable to interface intrinsic safety apparatus placed in hazardous area. Modules contain generally  one analogue channel and provide galvanic insulation between safe and hazardous area up to 375Vdc. Each module is equipped with two connectors, one is for circuitry related to intrinsic safety and the other is for the circuitry not related to intrinsic safety, that make possible either the connection to terminal boards, made up of a mounting chassis and connectors for the supply and the safe/hazardous areas connections, or the direct connections to the module with suitable female connectors type DIN B/3. The model HiC2025 is suitable to supply a 4 ÷ 20 mA SMART transmitter and the module HiC2031 is suitable to drive a  4 ÷ 20 mA I/P (current to pressure converter).

Electrical characteristics of module

Non intrinsically safe circuits

  • Um                        :           253Vrms
  • Tamb                       :           -20°C ÷ +60°C
  • Rated voltage Un     :           19 ÷ 30 Vdc        
Annex: Information about the intrinsic safety electrical parameters has to be taken from the annexe " Intrinsic safety electrical parameters - HiC" of this certificate.
