Another feature of the ICS that facilitates advanced system design is the integration of an 8-position “T” connector into the base of the packaging. This “T-BUS” connector sits in the well of the DIN-Rail and is connected to other T-BUS connectors there, one for every module to be incorporated in an application. The T-BUS can be connected to either or both communication protocols and power. This can be done through aforementioned integrated connection technology or separately through a field wireable connector that can be connected directly to the T-BUS. The contacts in the T-BUS are gold plated to ensure integrity. Incorporating the T-BUS facilitates scalable designs for users to maximize application flexibility. If more I/O or communication devices are needed, simply add more modules that are powered and networked through the T-BUS.
