Product Description
The Allen-Bradley 1771-A1B/B (96815203) is a Series B 4-slot I/O chassis designed for the PLC-5 1771 I/O platform. It provides the mechanical enclosure, parallel backplane bus, and power distribution path required for installing 1771 digital, analog, and specialty modules.
As a compact chassis, it is commonly used in small local I/O systems, remote I/O drops via 1771-ASB adapters, or machine-level control panels where limited I/O capacity is required. The Series B revision incorporates mechanical refinements and improved module compatibility compared to earlier releases.
This chassis is an open-style, panel-mounted unit and requires an external 1771-P series power supply for operation.
