Allen-Bradley 1764-24BWA MicroLogix 1500 Processor

Allen-Bradley MicroLogix 1500 base controller, catalog 1764-24BWA, pairs a 1764-LSP processor with a 12-input/12-output base for compact discrete-control tasks. The I/O provides 12 digital inputs and 12 relay outputs, with line power from 85–265 VAC and 24 V DC input options for the field I/O; the unit can expand up to 512 I/O total when used with compatible MicroLogix 1500 expansion options. A single RS-232 serial port (Channel 0) is included on the 1764-LSP processor, accessible via the mini-DIN connector. Physical dimensions are 6.62 in W × 3.43 in D × 5.43 in H, and mounting supports both DIN rail and panel installations. Operating temperature range is 32 to 131°F (0 to 55°C). This configuration serves straightforward automation needs where a small, self-contained PLC with discrete I/O and basic serial communication is sufficient, and is part of the MicroLogix 1500 family designed for economical, compact control solutions.
