The Allen-Bradley MicroLogix 1761-L32BBB is a compact programmable logic controller designed for small-scale automation tasks within factory or process environments, integrating power, memory, I/O channels, and communication ports within a single unit to eliminate the need for additional modules. Operating between 20.4 to 26.4 Volts DC, it features 32 discrete input/output points and supports peer-to-peer networking via its RS-232 and DH-485 ports, while also accommodating high-speed communications through its DeviceNet interface. With a fast execution time of 1.56 milliseconds and the capacity to handle up to 500 instructions, this controller is optimized for efficient discrete control operations, leveraging 1K EEPROM memory, 12 basic logic instructions, and advanced functionality through its 43 applied control and 14 application-specific instructions.
