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. 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. The ControlLogix chassis which are compatible and work with the 1756-L72 controller include the 1756-A4K, 1756-A7K, 1756-A4, 1756-A13, 1756-A7, 1756-A10, 1756-A13K, 1756-A10K, 1756-A17K, and the 1756-A17. Additionally, this controller has a full-speed 2.0 USB port as well as a 4-character alphanumeric display to view the current status.

About 1756-L72
The 1756-L72 controller is a standard controller that is meant to be used with a standard ControlLogix controller system. This part has been designed by Allen-Bradley and it is designed to provide a high-efficiency performance along with a high level of compatibility with different applications and communication methods. This controller provides 500 different connections and it comes with a non-volatile SD card. It is recommended to leave this card inserted so that it can operate with a higher memory capacity than average. One of the advantages of leaving this card installed is that if a fault occurs, the diagnostics data can be written in it. The Allen-Bradley 1756-L72 standard controller comes with different status displays and status indicators that show the current status of both the controller and its connections with different equipment.
The Allen-Bradley 1756-L72 standard controller can be used in an armored ControlLogix system that consists of this controller that is installed with an EtherNet capable communication module in an IP 67 rated protective housing on a machine. Some of the programming languages that are supported are the relay ladder, structured text, and function block languages, and a language called the sequential function chart languages. This specific controller can be installed in a chassis that contains more than one controller. The installation process is not complex but it is recommended to have a technician install the controller to ensure that it is done correctly.
