The Allen-Bradley 5150RS5 is a pyramid integrator remote I/O scanner module that is also referred to as the 5150-RS5 scanner module. It features the ability to read and to write to the I/O image tables using the logic processor on the same chassis and the ability to do scans that are independent and also asynchronous to the program scan process. The 5150RS5 scanner module also has I/O image files available where input data and output data are stored, as well as a scanner memory where the internal storage data, block-transfer control data, and block-transfer control information are saved.

This particular scanner module is compatible with the Allen-Bradley remote I/O adapters that belong to the 1771 series and features a local I/O channel which allows users to directly link the scanner module to the 1771-ALX adapter present on the 1771 I/O chassis. Operators can also use the 5150RS5 scanner module with any Allen-Bradley remote I/O link, any Pyramid Integration Chassis, and any Vision Platform. This scanner module is also compatible with various universal I/O products from the same manufacturer. If users want to connect this scanner module to a compatible I/O adapter, a 1770-CD cable with a 10,000-foot or 3048-meter length at maximum is required. The 5150RS5 scanner module is also equipped with two switch assemblies that offer users a more convenient configuration, as well as three diagnostic status indicators that are dedicated to its diagnostic information and the faults detected, specifically in terms of I/O rack faults and adapter faults. Note that this scanner module has a maximum power requirement of 5 Volts DC.
