More Information

Overview Manuals Spur Interfaces Line & Ring Diagnostics Field Housing

Features:

  • Eight short-circuit-proof spurs distribute one process-fieldbus main line to connected instruments.
  • Automatic bus termination supports line and ring topologies without a separate external terminator.
  • Main-line, spur, and termination indicators separate fieldbus faults at the installation point.
The distributor carries either PROFIBUS PA or FOUNDATION Fieldbus H1 while maintaining a uniform 31.25 kbit/s fieldbus path.

Branch current limiting and chatter suppression keep an unstable instrument connection from repeatedly disturbing the common segment.

Two main-line entries and eight field exits place the topology junction, termination logic, and local indication in one sealed assembly.

The Siemens 6ES7157-0AG82-0XA0 AFD8 Active Field Distributor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
Siemens 6ES7157-0AG82-0XA0 AFD8 Active Field Distributor Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

Protected Field-Device Branches

  • Eight outputs: Separate screw-terminal spurs connect as many as eight field devices to the shared segment.
  • Fault containment: Current limiting prevents one branch short circuit from becoming a direct fault across the remaining spurs.
  • Chatter control: Suppression logic stops a recurring branch fault from repeatedly reconnecting to the fieldbus.
  • Cable boundary: Each M16 entry accepts the documented cable and conductor ranges before termination inside the enclosure.

Main-Line Topology Handling

  • Pass-through path: Two main-line terminal groups carry the process fieldbus into and onward from the distributor.
  • Line topology: The automatic terminator closes the bus when the distributor is located at the end of a line.
  • Ring topology: Termination changes with the intact or interrupted state of the two-sided ring connection.
  • Shared protocols: The same wiring structure carries PROFIBUS PA or FOUNDATION Fieldbus H1 at 31.25 kbit/s.

Local Status and Fault Indication

  • Trunk state: Dedicated indicators show main-line activity and a detected main-line failure.
  • Branch state: Spur indicators identify the status or fault condition of the individual field connections.
  • Termination state: A separate indication confirms the automatic bus-termination function.
  • Service focus: The indicator grouping helps isolate a trunk, branch, or termination issue at the field distributor.

Outdoor-Style Installation Boundary

  • Enclosure: The IP66 assembly protects the internal distribution electronics from dust and powerful water jets.
  • Temperature: Operation is specified from -40 to +70 °C for exposed process-area conditions.
  • Humidity: The documented operating limit reaches 95% relative humidity.
  • Terminal access: Main-line and spur wiring terminate inside the common sealed field housing.
Description
Siemens 6ES7157-0AG82-0XA0 is an AFD8 active field distributor that divides a PROFIBUS PA or FOUNDATION Fieldbus H1 main line into eight instrument spurs. Each outgoing branch is current-limited and short-circuit-proof so a branch fault is confined at the distributor.

Automatic termination in 6ES7157-0AG82-0XA0 adapts the main-line connection for either line or ring topology. Two main-line terminals let the fieldbus pass through the housing, while the termination state is shown with its own diagnostic indication.

For maintenance, 6ES7157-0AG82-0XA0 provides status information for the main line, a main-line failure, every spur, and the termination function. Chatter suppression prevents a repeatedly faulting spur from cycling the shared field segment.

The IP66 housing of 6ES7157-0AG82-0XA0 uses M16 cable entries and screw terminals for both trunk and field wiring. Its -40 to +70 °C operating range supports installation near field devices rather than only inside a conditioned cabinet.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How does Siemens 6ES7157-0AG82-0XA0 keep one shorted instrument branch from disturbing the other spurs?
Current limiting in Siemens 6ES7157-0AG82-0XA0 confines a short circuit to the affected spur, while chatter suppression blocks repeated reconnection.
When 6ES7157-0AG82-0XA0 is placed at the end of a line or inside a ring, how is termination handled?
The automatic terminator in 6ES7157-0AG82-0XA0 adapts to the documented line or ring topology without a separate external terminator.
What branch-current limits must be checked before loading all eight outputs of Siemens 6ES7157-0AG82-0XA0?
Siemens 6ES7157-0AG82-0XA0 permits up to 60 mA per spur and 480 mA total across the connected field devices.
Which cable and conductor sizes fit the field entries on 6ES7157-0AG82-0XA0?
The M16 entries on 6ES7157-0AG82-0XA0 accept 4 to 9 mm cable and 0.2 to 2.5 mm² conductors.
If a branch indicator reports a fault on Siemens 6ES7157-0AG82-0XA0, which other status points help locate the problem?
Siemens 6ES7157-0AG82-0XA0 separately indicates main-line state, main-line failure, each spur, and the automatic termination function.
Can 6ES7157-0AG82-0XA0 be selected for either a PROFIBUS PA or FOUNDATION Fieldbus H1 segment?
Yes. 6ES7157-0AG82-0XA0 carries either documented protocol at 31.25 kbit/s through the same protected field-distribution structure.
