PRODUCT DESCRIPTION
6ES7157-0AF81-0XA0 Active PROFIBUS PA Field Distributor
Siemens 6ES7157-0AF81-0XA0 is a active profibus pa field distributor in the SIMATIC DP/PA AFD range. It is intended for compatible industrial automation projects requiring the documented PROFIBUS PA field-device distribution.
The AFD provides four PA spur lines in the documented redundant PA segment. It monitors main-line and spur-line conditions and limits each spur to 60 mA. The connected PA field devices must be outside the hazardous area, with segment loading and the associated couplers selected to match the permitted design.
