The Allen-Bradley 1756-L73XT is a robust ControlLogix-XT controller specifically designed to withstand harsh and corrosive environments, thanks to its protective coating. It operates optimally with the FLEX I/O-XT system, maintaining functionality in temperatures from -20 to 70 °C. Equipped with 8 MB of user memory and 0.98 MB of I/O memory, this controller supports extensive application needs without a replaceable battery. Featuring a continuous isolation voltage of 30 V, it endures up to 500V AC, ensuring reliable performance even in demanding conditions. With compact dimensions—just a quarter kilogram and a single slot width—it offers flexibility in chassis-based modular installations. The controller supports USB data transfer at speeds up to 12 Mbps, drawing minimal power and boasting efficient thermal dissipation. Suitable for both general and low-temperature applications, the 1756-L73XT does not offer power supply redundancy but operates with standard power options like the 1756-PA30XT. It copes with extreme non-operating temperatures and tolerates significant physical stress, affirming its durability and resilience for industrial use.
