Why Choose the ABB INS-TB Tap-Off Box Module?
The ABB INS-TB is a dedicated InSite Tap-Off Box module designed for data-centre busway and distributed energy-monitoring applications. It converts the ABB InSite bus connection to an RJ45-based link, allowing current sensors and other compatible monitoring components to be installed in individual tap-off boxes without requiring a complete control unit in every box.
With an ABB SCU200 installed in the main or master box, INS-TB modules can extend the monitoring architecture across multiple tap-off points. The modules support a daisy-chain arrangement and allow the SCU200 system to be extended over distances of up to 70 m, providing an efficient architecture for distributed busway monitoring.
The INS-TB is a passive device with InSite bus and proprietary 10BASE-T RJ45 connectivity, requiring no separate local power supply. Its compact single-module DIN-rail format makes it straightforward to integrate within tap-off enclosures. ABB order code 2CMA268075R1000 identifies this dedicated InSite Tap-Off Box module.

Distributed Monitoring for Data-Centre Busway Systems
Data-centre busway installations can contain numerous tap-off boxes distributed along the power-distribution route. The ABB INS-TB enables compatible sensors within these boxes to communicate back to a central InSite control architecture, reducing the need to install a separate SCU200 control unit at every monitoring point.
By converting the InSite bus connection for transmission through RJ45 cabling, INS-TB modules can be arranged in a daisy chain between the master and individual tap-off boxes. The final module includes a switch setting for terminating the chain, while the overall architecture can extend the monitoring capabilities of the master SCU200 across distances of up to 70 m.
