Features:
- The coupler converts a 45.45 kbaud PROFIBUS DP physical layer to a 31.25 kbaud PA segment.
- A 31 V DC, 1 A output powers connected non-Ex PROFIBUS PA field devices.
- Separate DP, PA, and supply indicators identify the operating state of both network sides.
Siemens 6ES7157-0AC82-0XA0 joins PROFIBUS DP control traffic to one powered PA field segment.
The PA output of 6ES7157-0AC82-0XA0 supplies field devices while the current budget limits their combined demand.
The switchable terminator on 6ES7157-0AC82-0XA0 defines whether the coupler ends or passes through the PA trunk.

Physical-Layer Conversion
- DP side: The controller network reaches the coupler at the documented PROFIBUS DP transmission rate.
- PA side: The field segment operates at the fixed PROFIBUS PA rate.
- Protocol path: The coupler transfers fieldbus telegrams while changing the electrical transmission method.
- Non-Ex scope: Connected PA devices remain outside the hazardous-area application covered by Ex couplers.
Segment Voltage and Current Budget
- Supply input: A 24 V DC feed powers the coupler and its PA supply circuitry.
- PA output: The field terminals provide 31 V DC within the documented tolerance.
- Current limit: All connected field devices together remain within the 1 A PA output.
- Device count: The segment supports no more than 31 devices and may support fewer when current demand is higher.
PA Trunk Connection Rules
- P+ and P−: The two field conductors connect with the documented polarity.
- Cable shield: The braided shield is clamped at the provided cable grip.
- Terminator ON: Enable termination when the coupler is at the physical end of the PA segment.
- Terminator OFF: Disable it only when the PA trunk continues to another correctly terminated endpoint.
Supply and Bus-Side Diagnosis
- ON indicator: The green LED confirms the 24 V DC supply is present.
- DP indicator: The yellow DP LED reports monitoring of the controller-side network.
- PA indicator: The yellow PA LED reports monitoring of the field-side segment.
- Fault isolation: Supply, DP wiring, PA wiring, termination, and field-device current are checked as separate paths.
