£328.70
Why Choose the ABB MRP31.0 Modbus RTU Interface?
The ABB MRP31.0 is a dedicated Modbus RTU communication interface for the ABB UMC100.3 Universal Motor Controller. It enables the UMC100.3 to connect to a Modbus RTU network, allowing motor-control information and commands to be exchanged with compatible PLC, automation and supervisory control systems.
Designed as part of ABB's Universal Motor Controller communication architecture, the MRP31.0 can be mounted directly onto the UMC100.3 or installed separately using the compatible SMK3.0 mounting kit. It operates from a 24 V DC control supply and uses screw terminals for secure industrial wiring.
ABB order code 1SAJ251000R0001 identifies this exact MRP31.0 Modbus RTU interface. Its compact 22.5 × 64 × 54 mm housing, IP20 protection and low 39 g net weight make it a practical communication module for intelligent motor-control installations.

Modbus RTU Connectivity for Intelligent Motor Control
Modbus RTU remains widely used for industrial serial communications, allowing controllers and field devices to exchange operating information over a common network. The ABB MRP31.0 provides this communication link for the UMC100.3, enabling the intelligent motor controller to participate in a Modbus RTU automation architecture.
The ability to mount the interface directly on the UMC100.3 or separately using the SMK3.0 kit provides installation flexibility for both fixed and modular control-panel designs. This makes the MRP31.0 suitable for motor control centres, industrial machinery and automated systems where centralised communication with motor controllers is required.
Typical Applications
- ABB UMC100.3 Universal Motor Controller installations.
- Modbus RTU industrial automation networks.
- Motor control centres and switchgear assemblies.
- PLC-controlled machinery and production equipment.
- Process automation and material-handling systems.
- Remote motor monitoring and control architectures.
