More Information

Overview Manuals Bus Conversion Fieldbus Power Ex Parameters Status Indication

Features:

  • PROFIBUS DP to PROFIBUS PA coupling
  • 110 mA fieldbus output for up to 31 devices
  • Ex [ia] field connection with galvanic isolation
Siemens 6ES7157-0AD82-0XA0 is the FDC157 Ex [ia] coupler that joins a PROFIBUS DP controller network to a PA fieldbus segment.

The coupler converts the DP communication path to the 31.25 kbit/s IEC 61158-2 physical layer and supplies current to the connected PA devices.

Dedicated LEDs show DP activity, PA activity and 24 V supply state, while isolation separates the two bus sides from the remaining circuits.

The Siemens 6ES7157-0AD82-0XA0 FDC157 Ex [ia] DP/PA Coupler may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

DP and PA Data Paths

  • Controller side: PROFIBUS DP connects through a 9-pin Sub-D interface.
  • DP rate: The controller-side path operates at up to 45.45 kbit/s.
  • Field side: The IEC 61158-2 connection operates at 31.25 kbit/s.
  • Coupling role: The unit transfers communication between the different physical layers without combining their electrical circuits.

PA Segment Loading

  • Output current: The PA connection supplies 110 mA in total.
  • Device count: Up to thirty-one field devices can be connected.
  • Load calculation: The combined device current must remain within the coupler output.
  • Incoming power: A 24 V DC input supplies the coupler electronics and fieldbus output.

Intrinsically Safe Output

  • Maximum Uo: The fieldbus open-circuit voltage is limited to 15 V.
  • Maximum Io: The documented short-circuit current is 247 mA.
  • Maximum Po: Output power is limited to 1.95 W.
  • Isolation: The DP and PA interfaces are galvanically separated from the remaining circuitry.

Operating-State Checks

  • DP LED: A yellow indicator identifies activity on the controller-side bus.
  • PA LED: A separate yellow indicator reports fieldbus-side activity.
  • Supply LED: The green 24 V indicator shows the incoming power state.
  • Diagnostics: Device diagnostic information is available through the PROFIBUS system.
Description
Siemens 6ES7157-0AD82-0XA0 is the FDC157 Ex [ia] DP/PA coupler for connecting a PROFIBUS DP system to an IEC 61158-2 fieldbus segment such as PROFIBUS PA. It translates the controller-side DP communication rate to the fixed PA transmission rate used by field devices.

Fieldbus power from 6ES7157-0AD82-0XA0 is delivered on the PA connection with a total output-current limit of 110 mA. Up to thirty-one field devices can share the segment, but the sum of their bus current remains bounded by that coupler output.

Separate DP, PA and 24 V indicators on 6ES7157-0AD82-0XA0 distinguish controller-side traffic, fieldbus activity and incoming power. The DP and PA interfaces are electrically isolated from the remaining circuits, while the documented Ex output values define the intrinsically safe field connection.

Which two networks does 6ES7157-0AD82-0XA0 connect?
The 6ES7157-0AD82-0XA0 connects a PROFIBUS DP controller side to an IEC 61158-2 fieldbus segment such as PROFIBUS PA.
Why must the current budget be checked before adding devices to 6ES7157-0AD82-0XA0?
The 6ES7157-0AD82-0XA0 can address up to thirty-one field devices, but their combined bus current must stay within its 110 mA field output.
What should be connected to the 9-pin Sub-D port on 6ES7157-0AD82-0XA0?
The 9-pin Sub-D connector on 6ES7157-0AD82-0XA0 is the PROFIBUS DP interface, not the PA fieldbus connection.
How can an installer distinguish bus activity from power state on 6ES7157-0AD82-0XA0?
The 6ES7157-0AD82-0XA0 uses separate yellow LEDs for DP and PA activity and a green LED for the 24 V supply.
Which ambient temperature range applies to 6ES7157-0AD82-0XA0 in operation?
The 6ES7157-0AD82-0XA0 is specified for operation from -25 to +60 °C.
