ABB PL810P 3BDH000311R0101

ABB PL810P 3BDH000311R0101

Product Overview
The ABB PL810P is a Power Link Module used in ABB industrial control and fieldbus infrastructure. It supplies power to a PROFIBUS PA segment and links the PROFIBUS PA fieldbus to an ABB head station or linking device. The module enables PROFIBUS PA devices to receive bus power and communicate through a 31.25 kbit/s PA segment. It is designed for process automation, field instrument integration, and distributed I/O applications where PROFIBUS PA is used.

Working Principle
The PL810P receives 20 to 35 V DC supply power and conditions it for the PROFIBUS PA segment. It provides up to 400 mA to connected PA field devices while maintaining the 31.25 kbit/s communication level defined by IEC 61158-2. Data from PA devices is passed through the linking device to the PROFIBUS DP or head station network. The module does not execute user logic; it acts as a physical layer power and communication link between the PA segment and the higher-level bus.

Installation Requirements

  • Install according to the ABB PL810P installation manual.
  • Verify compatibility with the connected head station or linking device.
  • Supply 20 to 35 V DC within the specified tolerance.
  • Connect the PROFIBUS PA segment to the correct fieldbus terminals.
  • Wire the link to the head station using the specified terminals.
  • Ensure proper grounding and shielding for PROFIBUS PA cabling.
  • Observe Zone 2 installation rules if used in hazardous areas.
  • Confirm the number of connected PA devices does not exceed segment current limits.

Precautions for Use

  • Do not exceed the 400 mA PROFIBUS PA segment current limit.
  • Verify that the head station or linking device supports the PL810P.
  • Do not use the module as a general-purpose PLC CPU.
  • Maintain correct polarity for supply and bus connections.
  • Confirm ATEX and Zone 2 requirements with the system integrator.
  • Use shielded PROFIBUS PA cable and proper termination.
  • For exact environmental ratings, terminal assignments, and certification limits, refer to the official ABB PL810P documentation.
