Allen-Bradley 1756-L72S is the GuardLogix 5570 controller, part of the Logix5000 series of controllers. It is a ControlLogix controller with security controls. It is a dual-processor solution that must be used in conjunction with the 1756-L7SP safety module to meet SIL 3 or Cat standards. 4/PLe Safety standard. The Security Partner controller is automatically configured to benefit individual projects. It has excellent processing power and motion speed as well as high-performance logic. It has a USB port for communication. It supports up to 500 controller connections. The 1756-L72S controller has 4MB of user memory, 2MB of security memory, and 0.98MB of I/O memory. It can support 128,000 digital I/ OS and 4,000 analog I/ OS. It consumes 2mA of current at 5.1V DC and 1mA at 800.5V DC. It has a power consumption of 2.5W and a heat dissipation of 8.5 BTU/ hour. It weighs 0.55 pounds and has an isolation voltage of 30V (continuous) for basic insulation. It can be installed in any slot in the ControlLogix 1756 case, or multiple controllers can be installed in the same case. For secure communication, it uses ControlNet, DeviceNet, or EtherNet/IP networks. The 1756-L72S controller can control or monitor I/O through the backplane or through the I/O link. For controller diagnostics, it has a front display that provides runtime information. It operates using energy storage modules, which means there is no need for lithium batteries. A 1 GB (1784-SD1) secure digital card is pre-installed as an optional non-volatile memory, expandable up to 2 GB (1784-SD2).

The Allen-Bradley 1756-L72S is a 5570 GuardLogix programmable Automation controller (PAC). The controller has both standard and safety controller functions. This controller is the master controller and is used with a security partner with catalog number 1756-L7SP or 1756-L7SPK to reach Security Integration Level (SIL) Category Level (CL) 3/ Performance Level e (PLe) /Cat. 4. Rating. With the 1756-L72S, unlike dedicated safety controllers, standards and safety items are integrated in a single file.

The 1756-L72S has a large-capacity standard memory and a dedicated security memory. These memory areas include 4 MB of user memory, 2 MB of safe memory, 0.98 MB of I/O memory, and 1 GB of non-volatile memory, provided by the 1784-SD1 that came with the controller. It enables the 1756-L72S to connect up to 128,000 input and output (I/O) signals, which may consist of 128,000 discrete I/ OS and 4,000 analog I/ OS.

The 1756-L72S is an environmentally friendly controller because it is equipped with a modern energy storage module instead of a traditional lithium battery to retain random access memory (RAM). These memory storage modules include the 1756-ESMCAP that comes with the controller; The 1756-ESMNSE is a removable, residual-free WallClockTime backup power supply, or the 1756-ESMNRM is non-removable, helping to prevent USB connections and SD card use to help protect the controller.
