The Allen-Bradley 1756-L72 is part of the ControlLogix programmable automation controllers Series A. It comes with 4 MB of user memory for data and logic as well as an I/O memory of 0.98 MB. This controller comes with 1 GB SD card called the 1784-SD1 which can be used as a non-compulsory nonvolatile storage memory. It is upgradeable to 2 GB through the 1784-SD2 card if more storage space is needed. The 1756-L72 controller features 30 Volts of continuous isolation voltage and it has also been typing tested for 60 seconds at 500 Volts AC. This controller comes with 800 mA of current at 5.1 Volts DC, and 5 mA of current at 1.2 Volts DC draw. The dissipation of power in the 1756-L72 controller is approximately 2.5 Watts while the thermal dissipation is 8.5 BTU/hour. The Allen-Bradley 1756-L72 has a storage temperature ranging between -40 and 85 degrees Celsius, even though it has an operating temperature ranging from 0 to 60 degrees Celsius. The controller has 30 g of operating shock, 2 g of vibration at 10 to 500 Hertz, and 50 g of non-operating shock. The Allen-Bradley 1756-L72 controller comes equipped with 3 different capacitor energy storage modules. The 1756-ESMCAP/1756-ESMCAPK removable module is present in every controller.

The 1756-ESMNSE/1756-ESMNSEK is also removable and it has no residual WallClockTime power backup. The 1756-ESMNRM/1756-ESMNRMK is the only non-removable module which helps in preventing the need for SD cards and USB connections thus securing the controller. The controller features several communication options including the Data Highway Plus, SynchLink, Remote I/O, DeviceNet, ControlNet, Ethernet/IP, and the 3rd party process and device networks. The connections of the USB ports are limited to configuration, programming, on-line edits, and firmware updates only. The Allen-Bradley 1756-L72 controller can be used with particular modules to come up with an Armor ControlLogix controller. This supports controller redundancy when it is paired with a matching controller within the same ControlNet network.
