1756-L71 Functional Description   

The Allen-Bradley 1756-L71 is a versatile and robust ControlLogix Programmable Automation Controller (PAC), designed to meet the demands of modern industrial automation. With a user memory capacity of 2 MB and 0.98 MB of I/O memory, it provides ample space for complex control processes. The controller features a 4-character alphanumeric display for easy real-time monitoring of controller diagnostics, run-time information, and module status, ensuring smooth operations. Additionally, the 1756-L71 CONTROLLOGIX 5580 CONTROLLER supports an open-style enclosure and includes a 2.0 full-speed USB port for seamless connectivity and configuration.

The 1756-L71 ControlLogix Programmable Automation Controller offers comprehensive communication options such as EtherNet/IP, DeviceNet, ControlNet, Remote I/O, Data Highway Plus, SynchLink, and third-party networks, providing high flexibility in integrating with various devices and networks. It comes equipped with a 1 GB non-volatile memory, which can be expanded to 2 GB by installing the 1784-SD2 SD card, offering even more storage capacity. The controller includes three capacitor energy storage modules, with two being removable, ensuring that data is retained without the need for a battery.

The 1756-L71 Smaller Memory-sized Controller is designed for high-performance applications, supporting up to 128,000 discrete I/O points and 4,000 analog I/O points, making it suitable for medium to large-scale automation tasks in industries like manufacturing and process control. It operates within a temperature range of 0 to 60°C and can withstand non-operating shocks up to 50G. For installation, the 1756-L71 requires a compatible ControlLogix chassis like the 1756-A4 or 1756-A10.

Allen-Bradley 1756-L71 is part of the Logix platform, offering efficient, scalable solutions for advanced automation, simplifying configuration and improving overall system performance.
