Pepperl + Fuchs: AS-interface module

Up to 62 modules with 248 standard PNP inputs and 248 SPST relay outputs can now be on a single network. Special sealed relays allow these modules to hold Class I Div 2 Groups A, B, C, D hazardous location approvals. Input power is switchable from internal mode where all inputs are powered from AS-Interface, to external mode where all inputs are powered externally.
