Allen-Bradley MicroLogix

Allen-Bradley MicroLogix is a family of compact programmable controllers for standalone machines and smaller automation systems. The range includes the 1000, 1100, 1200, 1400 and 1500 platforms, with architectures spanning fixed controllers with integrated I/O and modular processor-and-base arrangements. Selected models accept expansion I/O: 1762 modules serve compatible MicroLogix controllers, while the MicroLogix 1500 uses 1769 Compact I/O. Digital and analog signal handling, high-speed counting and pulse outputs depend on the selected controller. Communication capabilities include serial protocols and, on certain models, embedded Ethernet. RSLogix 500 supports ladder programming, data files and online troubleshooting. Typical functions include equipment sequencing, timing, interlocking, small process loops and data exchange with operator interfaces, with the controller and expansion modules matched to the required signal types.
