The Allen-Bradley 1775-L3 CPU module is a single-slot processor that is packed with powerful features. This Programmable Logix Controller (PLC) provides a greater control potential than other devices and it is responsible for program execution as well as memory management. Its features include over 70 programming instructions plus a single-slot processor module. The 1775L3A also has a highly flexible data table that is intended for use with floating point data, high-order integer data, as well as integer data. This processor has a super-fast program scan time, onboard diagnostics, in addition to a scheduled interrupt routine feature. There are diagnostic indicators that turn red when a failure occurs and green when everything is normal to allow for easy troubleshooting. The 1775L3A comes with a real-time clock and a calendar, so it does not require any external device to generate timed reports or programs. Besides, this module offers multiple contexts that cannot be found in other programmable controllers which enable the users to switch from one program to another more easily.

This Allen-Bradley Programmable Logix Controller (PLC) is equipped with a lithium battery that provides backup power for its memory. In the event that a 30-minute power outage occurs, the backup power offered by the battery is utilized by the 1775L3A’s memory to retain information. Even better, the lithium battery has the ability to last between 2 and 5 years, depending on the type of processor the operators are using, in addition to the amount of battery acid being used. Generally, this processor has powerful memory, scanner, communication, as well as power supply modules. Based on the user’s specific application needs, this PLC 3 module can be utilized for numerous configurations and expansion options. Unlike the conventional models, the 1775L3A is built on an advanced AMD microprocessor board. Communication module testing is carried out in a closed-loop configuration so that there are not any errors in communication.
