SIMATIC DP • PROFIBUS PA FIELD LINK
A non-Ex field coupler that links PROFIBUS DP to PROFIBUS PA and supplies the PA segment.
|
Siemens 6ES7157-0AC82-0XA0 is a SIMATIC DP field-device interface that couples PROFIBUS DP to a non-intrinsically-safe PROFIBUS PA segment. It converts the DP transmission rate to the fixed PA rate while supplying the connected PA fieldbus. The coupler provides a 31 VDC PA output with up to 1 A segment current, galvanic separation from the 24 VDC supply, integrated bus termination control and LED diagnostics for the DP side, PA side and incoming power. |
