BIPM is designed to insure intrinsic safety on a single (dual, BIPM-5K) AC/DC circuit. Barriers are typically used with different sensors driven in alarm and protection systems (in hazardous areas, classification 0,1,2, where flammable mixtures, of the categories IIA, group T1-T5 may be formed).

BIPM limit voltage and current in hazardous area circuits.
