Warom BPC-A-D Safety Barrier for Explosion-proof Keyboard and Mouse

The WAROM BPC-A-D is a DIN rail-mounted intrinsic safety (IS) barrier designed to provide safe connectivity between standard keyboards/mice and equipment operating in hazardous areas (e.g., Zone 1/2, Zone 21/22). It ensures spark and thermal energy limitation, preventing ignition risks in explosive atmospheres.
