Series ControlLogix
Module type GuardLogix controller
The 1756-L71SK controller is a GuardLogix integrated safe programmable automation controller of the 5570 series manufactured by Allen-Bradley. It provides scalable controller solutions capable of meeting various input/output and safety requirements in automated systems. The module has 2 MB of standard memory, 1 MB of safe memory, and 0.98 MB of input/output memory. The maximum number of digital inputs/outputs is 128,000, while the maximum number of analog inputs/outputs is 4,000. Its current consumption is 5 mA (1.2 volts DC) and 800 MA (5.1 volts DC). It has a power consumption of 2.5 watts and a heat dissipation of 8.5 VTU/ hour.

The Allen-Bradley 1756-L71SK GuardLogix controller consists of a master controller and a security partner that work together in a binary (1oo2) architecture design. The main controller consists of a central processor, memory, and input/output interfaces that communicate with security partners to implement safety-related functions in the GuardLogix control system. Its built-in USB communication port supports a variety of network protocols, including EtherNet/IP and ControlNet networks. When the controller is used in harsh environments, the conformational coating of the 1756-L71SK GuardLogix controller provides a layer of protection against contaminants, corrosive materials and/or moisture. The unit comes with a 1 GB SD card, and the HMI can be used to access the standard (but not secure) labels on this controller. Please note that the 1756-L71SK GuardLogix controller has a recommended operating temperature range of 0 to 60 degrees Celsius.
