The Allen-Bradley 1756-L71 ControlLogix Programmable Automation Controller is engineered to meet the rigorous demands of medium to large-scale automation applications within Factory and Process Automation environments. This PAC features a generous 2 MB of user memory alongside 0.98 MB of I/O memory, and comes equipped with a 1GB non-volatile SD card, upgradeable to 2GB using the 1784-SD2 card. Supporting up to 128,000 discrete and 4,000 analog I/O signals, it simplifies integration with a variety of networks such as EtherNet/IP, ControlNet, and DeviceNet. Notably, the 1756-L71 eliminates the need for batteries by utilizing removable capacitor-based energy storage modules for sustaining memory contents, and includes a comprehensive 4-character alphanumeric display for straightforward monitoring and diagnostics. Housed in an open-style enclosure, it offers extensive connectivity options, including a high-speed USB port and requires installation within a specified ControlLogix chassis for optimal operation.
