The Allen-Bradley 1764-24BWA MicroLogix 1500 Base Unit is the 12-channel 24V DC input, 12-relay-output base chassis for the MicroLogix 1500 family. It provides 12 24V DC input points and 12 relay outputs, and is powered from 120/240 VAC line power, making it suitable for compact discrete-control tasks in industrial panels. The base unit measures 6.62 in x 3.43 in x 5.43 in and supports DIN rail or panel mounting; it is designed to be paired with a MicroLogix 1500 processor (such as the 1764-LSP) to form a complete controller.
