SB3 Safety Barrier incl. DCA1192 Input/Output Module
Functions
The SB3 Safety Barrier limits the electrical energy between non-inherently safe and inherently safe circuits and thus prevents the ignition of gas mixtures by electrical sparks. The Safety Barrier must always be installed outside the explosive area. The DCA1192 Input/Output Module is the galvanical isolation between the fire panel and SB3 Safety Barrier.
