Logix 5573S Automation Controller 2M/1M

Description: The 1756-L71SK is a GuardLogix safety-rated controller from the ControlLogix 5573S family, intended for applications that require both standard control and integrated safety. It has 2 MB of regular user memory and 1 MB of safety memory, making it perfect for systems that integrate discrete, process, and motion control with SIL-rated safety functions. The suffix "SK" refers to conformal coating, which protects the controller's internal circuitry from moisture, dust, and corrosive contaminants—ideal for tough industrial applications. This controller supports SIL 3 / PLe safety applications and is programmed with Studio 5000 Logix Designer, which enables for the unified construction of standard and safety logic. It requires a safety partner module (usually the 1756-L7SP) to enable safety functions and meets global safety standards for use in industries such as automotive, chemical, and food processing.
