IO cards used in intrinsically safe instruments and flameproof instruments

2011-10-24View Original

Thread Content

Field intrinsically safe instruments are connected to the IO cards in the control room via safety barriers, while field flameproof instruments are connected to the IO cards in the control room as well. Are the IO cards in the control rooms used for these two instruments interchangeable? ?

The IO cards should be the same; it’s just that the safety barrier is used for the intrinsically safe circuit.
