Allen-Bradley 1762-L24BWAR MicroLogix 1200 Controller

Allen-Bradley 1762-L24BWAR is a compact 24-point programmable logic controller (PLC) from the MicroLogix 1200 family designed for standalone machine control and small automation applications. Operating on 120/240 V AC power, it integrates 14 digital inputs, 10 relay outputs, and an additional programming/HMI port for concurrent communications.

Digital I/O Configuration and High-Speed Capabilities

The controller features 14 24 V DC digital inputs divided into 10 standard inputs and 4 fast inputs capable of high-speed counting and pulse processing. The output section consists of 10 electromechanical relay outputs, providing dry-contact switching versatility for both AC and DC load circuits across industrial control setups.

Communication Ports and System Integration

Equipped with two communications interfaces, the 1762-L24BWAR allows simultaneous connections to programming software and an operator interface (HMI). The primary port handles standard DF1 protocol communications, while the additional port simplifies local configuration, monitoring, and operator display integration without disconnecting the main control network line.
