Allen Bradley 1756-L72S is a GuardLogix 5570 controller that is part of the Logix5000 series of controllers. It is a ControlLogix controller with security control functions. It is a dual processor solution that must be used in conjunction with the 1756-L7SP security module to meet the requirements of SIL 3 or Cat. 4/PLe safety standards. The security partner controller is automatically configured to benefit individual projects. It has strong processing power, motion speed, and high-performance logic. It has a USB port for communication. It can support up to 500 controller connections. The 1756-L72S controller has 4MB user memory, 2MB secure memory, and 0.98MB I/O memory. It can support 128000 digital I/Os and 4000 analog I/Os. It absorbs 2mA current at 5.1V DC and 1mA current at 800.5V DC. Its power consumption is 2.5W and thermal dissipation is 8.5 BTU/hr. It weighs 0.55 pounds and has a continuous isolation voltage of 30V, used for basic insulation. It can be installed in any slot of the ControlLogix 1756 chassis, and multiple controllers can also be installed in the same chassis. 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 diagnosis, it has a front panel display screen 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 nonvolatile storage and can scale up to 2 GB (1784-SD2).
