PROFIBUS DP to intrinsically safe IEC 61158-2 fieldbus coupling for extended-temperature applications.
Siemens 6ES7157-0AD82-0XA0 is the SIMATIC DP/PA Coupler Ex [ia] for connecting a PROFIBUS DP network to intrinsically safe IEC 61158-2 fieldbus segments such as PROFIBUS PA. The module supplies up to 110 mA to the PA segment and supports as many as 31 connectable PA field devices within the documented limits. It is intended for extended-temperature applications and provides diagnostic monitoring for DP activity, PA activity and the 24 V supply. Replacement planning should verify the exact suffix, product version, hazardous-area approvals, FISCO design, DP connector, PA wiring, power supply and enclosure requirements before installation.
