1756-L71 programmable automation controller

Описание

The 1756-L71 is a programmable automation controller.
It has the following key features and functions:
Display and monitoring: The controller has an on-board 4-character alphanumeric display. The display makes it easy to monitor runtime information and controller diagnostics, helping users understand the status and performance of the system in real time. This is useful for troubleshooting and system maintenance.
Physics and configuration: The 1756-L71 has an open chassis type and a full speed USB port. This means that users can easily connect other devices and modules to the controller for extension and customization. In addition, it supports controller redundancy, which improves system reliability and stability when paired with similar controllers in the same ControlNet network.
Processing power and range: The 1756-L71 is capable of processing up to 128,000 discrete input and output signals, and 4,000 analog input and output signals. This makes it suitable for industrial automation systems of all sizes and application scenarios.
Power and Storage modules: Unlike some other controllers **, the 1756-L71** does not use batteries to hold the contents of RAM or volatile memory. Instead, it employs a removable type of energy storage module based on capacitors. This design ensures that the controller can maintain data integrity and security in the event of a power failure or otherwise.
