Features:
- Six intrinsically safe spur lines distribute one process-fieldbus trunk to connected field devices.
- An integrated repeater restores communication between the trunk and protected spur circuits.
- Automatic termination supports line or ring fieldbus topology inside the IP66 assembly.
The FISCO barrier section limits the electrical conditions presented to each field-device spur while preserving the shared communication path.
Bounce-protection logic works with the short-circuit-proof outputs so a disturbed spur does not directly interrupt every branch on the distributor.
The enclosure combines distribution, signal repetition, and topology termination at one installation point for PROFIBUS PA or Foundation Fieldbus H1.
The Siemens 6ES7157-0AG83-0XA0 SIMATIC AFDiS Active Field Distributor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Protected Field Connections
- Branch isolation: Each of the six spur outputs has short-circuit protection for its connected field-device branch.
- Intrinsic safety: The FISCO barrier constrains the energy delivered from the trunk side to the spur circuits.
- Bounce control: Protection logic suppresses repeated reconnection behavior after a spur-side fault.
- Fault scope: A problem on one branch is contained at its spur rather than wired directly across all six outputs.
Trunk and Segment Arrangement
- Supported buses: The distributor works in PROFIBUS PA and Foundation Fieldbus H1 segment structures.
- Repeater path: The built-in repeater regenerates communication as it passes between the trunk and field spurs.
- Line mode: Automatic termination closes the bus at the appropriate distributor position in a line.
- Ring mode: The same termination function adapts when the trunk is arranged as a ring.
Distributor Connection Roles
- Trunk side: The incoming process fieldbus carries shared communication into the distributor.
- Spur side: Six outgoing branches connect individual field devices to the common segment.
- Barrier boundary: Energy limitation is applied before the field wiring leaves through each intrinsically safe spur.
- Integrated assembly: Repetition and termination remain inside the same housing as the distribution connections.
Housing and Installation Conditions
- Ingress protection: The IP66 housing protects the assembled distributor against dust and powerful water jets.
- Field location: The enclosure permits the protected spur split to be positioned near the connected instruments.
- Temperature design: The extended-temperature version is intended for conditions beyond a standard indoor cabinet device.
- Single assembly: The field barrier, repeater, spur outputs, and termination remain enclosed together.
