The 5130-KA is a data highway/data highway plus interface module manufactured by Allen-Bradley. The Allen-Bradley 5130-KA Interface Module is part of the line of Series A Interface Modules. The Allen-Bradley 5130-KA Interface Module forms the largest member of the PLC-5 family. The Allen-Bradley 5130-KA Interface Module is designed for additional DH/DH+ and serial communication capability by incorporating the Allen-Bradley Vision Platform/Pyramid Integration Chassis, and it does not provide a data table. Users can have up to 4 Allen-Bradley 5130-KA Interface Modules in a pyramid integrator chassis. The Allen-Bradley 5130-KA Interface Module is an advanced programmable controller capable of multi-processing and supervising control over other Allen-Bradley programmable controllers. The Allen-Bradley 5130-KA Interface Module merges with programmable controllers, computers, and other devices so that they can communicate and exchange data with one another quickly and easily.

The Allen-Bradley 5130-KA Interface Module has a cable system hardware interface that is responsible for transmitting data between the nodes. It utilizes peer-to-peer communication via a modified token-passing scheme known as floating master. The floating master scheme controls access to the Allen-Bradley 5130-KA Interface Module network and initiates messages at any given time. The Allen-Bradley 5130-KA Interface Module cable systems provide the users with the flexibility to design a communication network that suits a particular user need well. The first procedure in installing the Allen-Bradley 5130-KA Interface Module cable system is to attach a 3-position terminal block connector to the dropline. When removing the Allen-Bradley 5130-KA Interface Module, there is no need of removing the power supply from an Allen-Bradley programmable controller. The Allen-Bradley programmable controller usually continues to control its outputs even after the programmable controller is disconnected from the Allen Bradley 5130-KA Interface Module network.
