The Allen-Bradley 1756-L73SXT GuardLogix controller is part of the ControlLogix family by Rockwell Automation, designed with integrated safety control capabilities beyond those of standard ControlLogix controllers.
It supports both safety and standard communications across multiple industrial networks, ensuring flexible and secure system operation.
The 1756-L73SXT includes 8 MB of user memory and 4 MB of safety memory, supporting up to 128,000 total I/O channels.
During normal operation, it dissipates approximately 2.5 Watts (8.5 BTU/hr) of power and functions reliably in ambient temperatures up to 140°F (60°C).
The controller can be stored at temperatures up to 185°F (85°C) with a maximum relative humidity of 95%, non-condensing.
