Allen Bradley 1756-L71S is a GuardLogix 5570 controller that is part of the Logix5000 series of controllers. It is a ControlLogix controller with security features. 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, providing the main advantage for individual projects. It has strong processing power, motion speed, and high-performance logic. It has a USB port for communication and can support up to 500 controller connections. The 1756-L71S controller has 2MB user memory, 1MB safe 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.
1756-L71
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. For secure communication, it uses ControlNet, DeviceNet, or EtherNet/IP networks. The 1756-L71S 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 1756-ESMCAP and 1756-ESMCAPK 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).
