Why Choose the ABB INS-HUB InSite Expansion Module?
The ABB INS-HUB is a compact collector hub and expansion module designed for the ABB InSite energy management system with the SCU200 control unit. Supplied under ABB order code 2CMA278455R1000, it expands the InSite bus by allowing up to 64 additional devices to be connected through the system flat cable.
A standard SCU200 supports up to 32 InSite devices. Adding one INS-HUB increases this capacity by 64 devices, while up to two INS-HUB modules can be connected to a single SCU200, enabling an installation with up to 160 InSite bus devices. This makes the module particularly valuable for larger commercial, industrial and data-centre monitoring systems requiring extensive branch-level measurement and device integration.
The INS-HUB connects directly to the SCU200 and is powered by the control unit, simplifying installation without requiring a separate module power supply. Compatible InSite bus devices can include current sensors, digital I/O modules, smart auxiliary contacts and communication modules for motor-operated devices, providing a scalable architecture for comprehensive energy and electrical distribution monitoring.
Key Advantages
- Expands the ABB SCU200 InSite bus by up to 64 additional devices.
- Supports large monitoring systems with up to 160 InSite devices when two INS-HUB modules are used.
- Connects directly to the ABB SCU200 control unit.
- Powered directly from the SCU200, eliminating the need for a separate module supply.
- Supports current sensors, I/O modules, smart auxiliary contacts and compatible communication modules.
- Uses the established InSite flat-cable bus architecture for scalable system expansion.
- Compact 17.5 mm wide design minimises space requirements inside electrical panels.
Key Features
- ABB InSite collector hub / expansion module.
- 64 additional InSite bus device connections per INS-HUB.
- Standard SCU200 capacity expandable from 32 to 96 devices with one INS-HUB.
- Maximum of 2 INS-HUB modules per SCU200.
- Maximum system capacity of 160 InSite bus devices with two hubs.

Scalable Expansion for ABB InSite Energy Management
The ABB INS-HUB allows an InSite installation to grow beyond the standard device capacity of the SCU200. Each expansion module adds connections for up to 64 additional InSite bus participants, making it possible to monitor and integrate substantially more circuits and electrical devices without replacing the central control unit.
Devices connected through the expanded InSite bus can include current sensors, digital I/O modules, smart auxiliary contacts and communication modules for compatible motor-operated equipment. This scalable architecture makes the INS-HUB especially useful in installations with numerous monitored circuits, allowing energy, status and control information to be consolidated through the ABB InSite platform.
Typical Applications
- Expansion of ABB SCU200 InSite energy management systems.
- Large commercial and industrial electrical distribution boards.
- Data-centre power and branch-circuit monitoring.
- High-density current-sensor installations.
- Building energy-management and electrical monitoring systems.
- Distribution systems requiring extensive digital I/O and device-status monitoring.
