Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 6ES7157-0AG81-0XA0 is the SIMATIC Active Field Distributor AFD4 from Siemens' PROFIBUS PA / Foundation Fieldbus H1 portfolio. It serves as an interface between the main bus and up to four spur lines, providing short-circuit protection, automatic bus termination in both line and ring topologies, and supporting extended temperature operation. Installed in field environments, it is typically employed in process automation systems for distributing communication power to field devices in applications requiring localized branching and protection.
