Allen-Bradley 1764-24BWA MicroLogix 1500 Base Unit combines 12 24V DC digital inputs with 12 relay outputs in a compact base for MicroLogix 1500 systems, designed to be paired with a separate MicroLogix 1500 processor module to form a complete controller and powered from line voltage that tolerates 85–265 V AC. A front RS-232 serial port provides programming and local communication, and the base can be mounted on DIN rail or panel; its dimensions are 6.62 x 3.43 x 5.43 inches. The base supports up to 512 expanded I/O points when used with compatible modules, and typical power consumption is around 39 W.
