Why Choose the ABB SCU200 Control Unit?
The ABB SCU200, order code 2CCG001158R0001, is a compact DIN-rail control unit for the ABB InSite energy management system. Designed for intelligent energy and load management in sub-distribution and final distribution applications, it collects information from compatible field devices and provides a central platform for monitoring, data visualisation and system integration.
The SCU200 can integrate up to 16 Modbus RTU devices, 16 Modbus TCP devices and 32 InSite bus devices. Compatible equipment can include current sensors, digital I/O modules, smart auxiliary contacts, energy meters and network analysers, enabling electrical information from multiple devices to be consolidated within one compact control architecture.
An integrated InSite web server provides access to measurement and system information through a standard network connection. With Ethernet, RS485 and InSite bus interfaces, plus support for Modbus RTU, Modbus TCP/IP, REST API, DHCP, HTTPS and NTP, the SCU200 provides flexible connectivity for local monitoring and integration with higher-level energy or building management platforms.

Centralised Energy and Load Management with SCU200
The ABB SCU200 provides the central intelligence for an InSite energy management installation. It can collect electrical measurements and status information from compatible Modbus and InSite bus devices, allowing current sensors, I/O modules, smart accessories, energy meters and network analysers to contribute data to a common monitoring platform.
The integrated web server makes this information accessible through the network, while Ethernet, RS485 and supported open communication protocols enable connection to higher-level systems. Its modular architecture also allows compatible SCU200 metering, power supply and communication modules to be added where required, providing a scalable foundation for energy monitoring and load management projects.
