The 1756-L71SK controller is a 5570 series GuardLogix integrated safety programmable automation controller manufactured by Allen-Bradley. It provides scalable controller solutions that are capable of meeting various input/output and safety requirements in automated systems. This module has 2 Megabytes of standard memory, 1 Megabyte of safety memory, and 0.98 Megabyte of input/output memory. Its maximum number of digital input/output is 128,000 whereas its maximum number of analog input/output is 4000. Its current draw is 5 milliamps at 1.2 Volts DC and 800 milliamps at 5.1 Volts DC. It has 2.5 Watts of power dissipation and 8.5 VTU/hr of thermal dissipation.
The Allen-Bradley 1756-L71SK GuardLogix controller consists of a primary controller and a safety partner that function together in a One-Out-Of-Two (1oo2) architecture design. The primary controller comprises the central processor, memory, and input/output interface, and it communicates with the safety partner for safety-related functions in a GuardLogix control system. Its built-in USB communication port supports multiple network protocols, including the EtherNet/IP and ControlNet networks. The conformal coating of the 1756-L71SK GuardLogix controller provides a layer of protection against contaminants, corrosive material, and/or humidity when the controller is used in harsh environments. This unit is shipped with a 1-Gigabyte SD card and human-machine interface can be used to access standard (but not safety) tags on this controller. Note that the recommended operating temperature range for the 1756-L71SK GuardLogix controller is from 0 to 60 degrees Celsius.
