Features:
- The FDC157-0 couples a PROFIBUS DP controller path to a non-Ex PROFIBUS PA segment.
- A 31 V PA output supplies the connected segment within the stated current budget.
- Integrated diagnostics return coupler and segment states through the DP network.
The control network and powered fieldbus segment meet at one coupling point.
Redundant operation uses the documented paired arrangement rather than an independent local mode.
The IP20 assembly belongs inside the specified cabinet and temperature conditions.
The Siemens 6ES7157-0AC83-0XA0 SIMATIC DP FDC157-0 DP/PA Coupler may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Moving controller traffic onto the PA segment
- DP connection: The controller-side network exchanges cyclic data with the coupler.
- Protocol boundary: The coupler transfers that exchange to the lower-speed PA fieldbus.
- PA devices: Field instruments communicate on the powered non-Ex segment.
- Diagnostic return: Coupler conditions travel back through the integrated DP diagnostic slave.
Matching field load to the PA output
- Output voltage: The coupler establishes the documented PA bus voltage.
- Current budget: Device and cable demand share the available segment current.
- Non-Ex boundary: This article is the non-intrinsically-safe FDC157-0 version.
- Load check: Commissioning must confirm that the assembled segment stays within the output limit.
Using two paths in the supported arrangement
- Paired units: The documented redundancy layout uses two couplers for the fieldbus connection.
- Controller view: Diagnostic information lets the automation system distinguish the available paths.
- Shared segment: Both coupling paths serve the intended PA network rather than separate instruments.
- Wiring check: DP and PA connections must follow the approved redundant topology.
Applying the coupler inside its rated environment
- Cabinet mounting: The IP20 assembly requires the specified protected installation location.
- Temperature version: The exact article is the extended-temperature FDC157-0 version.
- Segment type: Only the documented non-Ex PA arrangement applies to this order number.
- Model suffix: The complete 0AC83-0XA0 code separates this coupler from later revisions.
