1SAJ530000R0100 ABB UMC100.3 Universal Motor Controller 24 V DC

Why Choose the ABB UMC100.3 Universal Motor Controller?

The ABB UMC100.3, order code 1SAJ530000R0100, is a 24 V DC Universal Motor Controller combining motor protection, control, diagnostics and communication capabilities in one compact device. Designed for intelligent motor management, it provides comprehensive supervision of low-voltage motors while reducing the amount of separate control and protection equipment required.

This UMC100.3 DC version provides an adjustable motor-current range of 0.24–63 A without external current transformers and supports both single- and three-phase motors. Integrated motor-protection functions are complemented by programmable application logic, detailed operating and diagnostic information and selectable trip classes for flexible adaptation to different motor starting characteristics.

The controller operates from a 24 V DC supply and includes six 24 V DC digital inputs, four digital outputs and one PTC input. Communication interfaces can be added for fieldbus and Industrial Ethernet networks, allowing the UMC100.3 to integrate into modern motor control centres, process plants and automated machinery.

Key Advantages

• Combines motor protection, control, monitoring and diagnostics in one intelligent controller.
• Wide 0.24–63 A motor-current setting range without external current transformers.

Intelligent Motor Protection, Control and Diagnostics

The ABB UMC100.3 integrates motor management functions that would traditionally require several separate devices. It supervises motor current and thermal loading, provides configurable motor-control functions and records service information including operating hours, number of motor starts and overload trips. Faults, warnings and a history of the latest 16 events provide maintenance personnel with detailed information for troubleshooting and preventative maintenance.

The UMC100.3 architecture can be expanded with additional I/O, voltage and analogue modules and connected to an ABB UMC100-PAN operator panel. Compatible communication interfaces support fieldbus and Ethernet networks, enabling motor status, commands, diagnostic information and operating data to be exchanged with PLC, DCS and plant automation systems.

Typical Applications

• Motor control centres and intelligent motor feeders.
• Pumps, fans and compressors.
• Conveyors and material-handling systems.
• Manufacturing and production machinery.
• Process-industry motor control.
• Industrial automation and distributed control systems.
• Applications requiring detailed motor diagnostics and maintenance data.
