This Galvanically Isolated Intrinsic Safety Barrier is the perfect complement to BEI encoders for hazardous environments. It is electrically compatible with all popular counters, PLCs and controllers, and it features isolation for power and three signal channels, as well as LED indicators for power and data – all in a single DIN rail package.
The BEI Barrier carries CENELEC, UL and cUL ratings and is suitable for long cable runs. Since it also carries a non-incendive designation per the National Electrical Code, it can be mounted in Class I, Division 2 areas.
This interface provides a means to connect a BEI Sensors Intrinsically Safe encoder from a Hazardous Zone where explosive gasses may exist, to a safe zone where a controller and other electrical equipment usually resides. It accepts a 5 volt input from the encoder and it is powered with a voltage from 5 to 28 volts and provides a 5 volt regulated output in the safe zone.
