The Allen-Bradley 1756-L72S is a robust and versatile GuardLogix 5570 controller within the Logix5000 series, designed for both standard and safety control applications. With its dual processor solution, it integrates seamlessly with the 1756-L7SP safety module to achieve SIL 3 or Cat. 4/PLe safety standards, allowing for streamlined project management by automatically configuring its safety partner. Boasting 4MB user memory, 2MB safety memory, and the ability to handle up to 128,000 digital I/O and 4,000 analog I/O signals, this controller excels in high-performance logic and motion applications. Featuring a USB port and supporting communication across ControlNet, DeviceNet, or EtherNet/IP networks, the 1756-L72S controller offers flexible installation within any slot of a ControlLogix 1756 chassis. Importantly, it uses state-of-the-art energy storage modules, eliminating the need for lithium batteries, and includes a 1GB Secure Digital card for non-volatile memory, expandable to 2GB.
