Why Choose the ABB SCU100 InSite pro M compact Control Unit?
The ABB SCU100, order code 2CCG000242R0001, is the sub-distribution control unit at the heart of the ABB InSite pro M compact energy monitoring system. Designed as a single access point for a sub-distribution board, it collects and aggregates information from compatible current sensors, digital I/O modules, meters and other field devices.
The SCU100 supports integration of CMS current sensors, ABB digital input/output modules and energy or power meters using Modbus RTU. Communication through Modbus TCP/IP and Modbus RTU enables collected electrical data to be made available to supervisory and energy management systems, supporting detailed monitoring of electrical distribution installations.
An integrated web-based interface provides a central platform for commissioning, configuration and monitoring, while the SCU100's internal power supply supports connected sensors and I/O modules. This combination makes the control unit a practical foundation for scalable branch-circuit monitoring, energy management and intelligent sub-distribution applications.

Centralised Monitoring for Intelligent Sub-Distribution
The ABB SCU100 provides the central intelligence required to turn individual monitoring components into an integrated sub-distribution monitoring system. Current sensors can provide branch-level electrical measurements, while digital I/O modules enable conventional accessories and devices with digital or pulse interfaces to become part of the monitoring architecture. Modbus RTU also allows compatible energy and power meters to contribute data to the system.
By aggregating this information and making it available through Modbus TCP/IP or Modbus RTU, the SCU100 provides a bridge between field-level electrical devices and higher-level supervision or energy management platforms. This architecture enables detailed visibility of electrical consumption and operating status while retaining the modularity required to expand the monitoring system as installation requirements develop.
