Brand Allen Bradley
Part Number/Catalog number 1756-L71K Series
Series ControlLogix
Module Type Processor module
The 1756-L71K module is the Allen-Bradley ControlLogix or GuardLogix module. The Allen-Bradley ControlLogix processor module consumes 2.6 watts. The device also comes with 2 megabytes of memory. The 1756-L71K module features a conformal coating that protects against adverse environmental conditions such as moisture. The unit has an isolation voltage of 30 volts continuous, while the housing type is open. The maximum I/O rating is 128,000 digital I/ OS and 4,000 analog I/ OS, while the I/O memory capacity is 0.98 MB. The processor module supports a USB port as a local programming port and comes with an energy storage module. The supported non-volatile memory is a secure digital card. The module supports embedded Ethernet ports.
The 1756-L71K module supports ControlNet, DeviceNet, and EtherNet/IP communication network options. It also provides excellent processing power and speed for motion control, making the module suitable for high-performance logic and redundant applications. The module can support up to 500 controller connections. To ensure the diagnostic process is simple, the module supports a front-facing display that provides the user with runtime information. Since the module supports energy storage modules, there is no need to connect it to a lithium battery.
