ABSTRACT:
An interface system interconnects a common power supply and plural data communications paths located in a safe environment to a plurality of load devices located in a flammable atmosphere. A module power attenuator attenuates the electrical power output level of the common power supply to a first predetermined level for application to the load devices. A digital signal attenuator attenuates the electrical power level between data communications paths to a second predetermined level for application to the load devices. Coupling devices are utilized to maintain electrical segregation but allow communication to and from the safe environment.
