Allen-Bradley PLC-5: 1771/1785 Series
The Allen-Bradley PLC-5, once a stalwart in industrial automation, has been discontinued, though it remains prevalent in existing applications. Introduced in the 1980s, it earned trust for its reliability, modularity, and user-friendly design.
Key Points:
-
The Reliable Veteran: Known for its reliability and ease of use, the PLC-5 was widely adopted across industries for tasks like machine control, process automation, and material handling.
-
Workhorse of Automation: Its modular design, featuring a central processor and various I/O modules for digital and analog signals, allowed for customization based on project requirements.
