The AB+MVI56-BAS module refers to a Modular I/O Communication Interface used in industrial automation and control systems. Specifically, it is part of the Allen-Bradley (AB) range of modules designed for use in automation systems to interface with programmable logic controllers (PLCs). The MVI56-BAS module is typically used in a Rockwell Automation system, helping to connect Allen-Bradley controllers to different types of networks or external devices.

Product Name:

Allen-Bradley MVI56-BAS (BAS module)

Product Description:

The MVI56-BAS module is a communication interface module designed to integrate Allen-Bradley ControlLogix or CompactLogix systems with third-party devices and networks. It serves as an interface to BAS (Building Automation Systems) protocols, making it easier to link industrial automation with building systems like HVAC, lighting, and security systems.

It uses an open architecture, typically for controlling or integrating industrial building systems through Modbus, BACnet, or other common protocols. The module provides bidirectional communication between a ControlLogix system and the various BAS protocols, improving control, monitoring, and data exchange.
