Allen Bradley MicroLogix 1400 PLC Models

A family of programmable logic controllers (PLCs) known as the Allen Bradley MicroLogix 1400 PLC is intended for small to medium-sized industrial automation applications. The MicroLogix 1400 series offers a variety of devices with various features and specifications to satisfy various application needs.

For its size and price, the MicroLogix 1400 controller is incredibly powerful. More intricate degrees of automation are possible because to advanced capabilities like high-speed outputs and batch recipe storing, pushing the boundaries of what may be regarded as single-machine control. Despite their compactness, these PLCs frequently run small pilot plant systems as well as multi-tank batch systems, central ingredient delivery, and multi-axis machine movements. The MicroLogix 1400 can only handle a certain number of applications because to its limited memory, I/O, and instruction capacity, but the available alternatives are robust enough to merit careful consideration before upgrading to a CompactLogix PLC.

Built-in LCDs are a feature of the Rockwell Automation MicroLogix 1400 PLCs. The ability to display a logo or welcome text while initialising the devices, the ability to view user-defined messages on the screen, and the ability to view the status of the inputs, outputs, and display of mathematical variables from the program are additional features that users of the MicroLogix 1400 controllers greatly value. 

Here are some of the most common MicroLogix 1400 models:
