The Allen-Bradley 1756-L85EP is a robust controller from the ControlLogix 5580 family, designed for both Series C and Series B chassis—though the latter requires attention to a reduced temperature range for optimal performance. It offers seamless Ethernet connectivity with support for link speeds of 10, 100, and 1000 Mbps and can manage up to 300 Ethernet nodes, all while providing 40 MB of user memory. With efficient power dissipation of 6.2 Watts and an ability to operate within a temperature range of 32 to 140 degrees Fahrenheit, the module is optimized for high-precision environments with humidity levels from 5 to 95%, and is compliant with the T4 ATEX temperature code for reliable vertical installation across varying industrial applications.
