Why Choose the ABB PDR31.0 PROFIBUS Termination Unit?
The ABB PDR31.0 is an active PROFIBUS DP bus termination unit designed to provide stable and reliable communication at the end of a PROFIBUS DP network. Supplied under ABB order code 1SAJ243000R0001, it forms part of the ABB 311531-FieldBusPlug product group and is designed for use with ABB motor control and fieldbus communication systems.
The PDR31.0 provides the active termination required by PROFIBUS DP installations where the associated PDP32.0 communication interface cannot itself act as an active bus terminator. By maintaining the correct electrical termination of the PROFIBUS segment, it helps support dependable data transmission and network stability in industrial automation and motor control applications.
Operating from a 24 V DC control supply, the PDR31.0 is designed for installation on an ABB SMK3.0 single mounting kit. Its compact 22.5 mm width, screw-terminal connections and IP20 construction make it suitable for installation within industrial control panels and motor control centres.

- Compact industrial design for control panels and motor control centres.
Reliable Active Termination for PROFIBUS DP Networks
Correct bus termination is essential for dependable PROFIBUS DP communication because it helps prevent signal reflections and communication disturbances at the ends of the network segment. The ABB PDR31.0 provides an externally powered active termination, allowing the PROFIBUS network to remain correctly terminated independently of the PDP32.0 communication interface.
The PDR31.0 is particularly useful in industrial motor control architectures where reliable fieldbus availability is important. When mounted on the ABB SMK3.0 adapter and supplied with 24 V DC, it provides the active termination required for stable PROFIBUS DP communication within control panels, motor control centres and automated production systems.
Typical Applications
- PROFIBUS DP industrial automation networks.
- ABB UMC motor control installations.
- Systems using ABB PDP32.0 PROFIBUS DP communication interfaces.
- Motor control centres and intelligent MCC systems.
- Industrial control panels and automation cabinets.
- Manufacturing and process automation systems.
