Allen-Bradley 1764-LSP PLC Processor

Allen-Bradley 1764-LSP MicroLogix 1500 Processor Module is the single-CPU element of the MicroLogix 1500 controller family, designed to be used with a MicroLogix 1500 base unit and I/O modules to form a compact PLC system. It delivers PLC program execution and serial communications for small automation tasks and is sold as a processor module rather than a standalone controller. The “S” in LSP denotes Single Serial Port, distinguishing it from dual-port models such as the 1764-LRP. The 1764-LSP provides about 7.65k words of user memory for program and data, enabling ladder logic and associated data handling in many applications. In a MicroLogix 1500 system, a controller is composed of a 1764-LSP (or 1764-LRP) processor plus a base unit, with expansion I/O modules available to tailor the system to the specific application.
