Technical Specifications
Version & Model Difference
The 1756-L81E is part of the ControlLogix 5580 series, which replaces the older ControlLogix 5560 series. Compared to the 1756-L61E (5560), the 5580 offers a faster processor (1.5 GHz vs. 800 MHz), more memory (2 MB vs. 1 MB), and enhanced communication capabilities. The 5580 series also supports a larger number of I/O points and has improved security features. Additionally, the 1756-L81E includes a built-in energy storage module, eliminating the need for a separate battery, unlike the 5560 series which required a battery for memory backup.
