The Allen-Bradley 1756-L72EROM Armor ControlLogix controller is an industrial powerhouse capable of managing up to 32 tasks with 1000 programs per task. It offers users 4 MB of data and logic memory, supported further by a 1 GB SD card for backup, and possesses substantial I/O capabilities with a digital and total I/O count each reaching 128,000 and a maximum analog I/O of 4000. Equipped with four EtherNet M12 Category 5E ports and one Type B USB 2.0 port, this controller facilitates up to 256 EtherNet/IP and 128 TCP network connections per module, while supporting a maximum of 500 controller connections. Although it lacks serial port communication and redundancy support, it features programming versatility with languages such as structured text, relay ladder, sequential function chart, and function block. Enclosed in a UL Type 4/4x housing, this robust unit measures 9.4 x 11.5 x 6.5 inches, weighs 7.04 kg, and operates optimally within a voltage range of 18-32V DC. Notably, the 1756-L72EROM has been type-tested for insulation robustness at 707V DC, confirming safety under severe conditions, and has operational endurance to humidity levels of 5-95%, temperatures from 0-60 °C, and vibrations of 2 g at 10-500 Hz.
