The Allen-Bradley 1756-L73EROMS is an Armor GuardLogix 5570 controller with safety control capabilities up to Safety Integrity Level (SIL) 3 and performance level PLe (Category 4). It supports the same global certification and environmental rating as ControlLogix and GuardLogix controllers, while offering additional IP67 (protection rating) and UL Type 4/4x dust cases. It includes two separate EtherNet/IP and DLR (Device-level Ring Network) network channels to quickly recover from network connection loss if one connection fails. It provides easy access to controller mode switches, USB ports, secure digital (SD) card slots, and power switches.

The 1756-L73EROMS controller has 8 MB of user memory, 4 MB of safe memory, and 0.98 MB of I/O memory. It can support up to 128,000 digital I/ OS and 4,000 analog I/ OS. It measures 9.4 x 11.5 x 6.5 inches. It weighs 15.725 pounds. It has a nominal input voltage of 24V DC and can be used to power other On-Machine products through. It has four M12 Class 5E Ethernet ports and one USB 1.1 full speed (12Mbps) USB port. It can be installed in any slot on the ControlLogix 1756 chassis, or multiple controllers can be installed in the same chassis. For standard and secure communication, it uses an EtherNet/IP network with 256 EtherNet/IP and 128 TCP connections.

The 1756-L73EROMS controller simplifies cabling and reduces cabinet hardware, so no special tools or personnel are required to replace components. A 1 GB (1784-SD1) secure digital card is pre-installed as optional non-volatile storage, expandable up to 2 GB (1784-SD2). It also features new lenses that provide better status indications, display readability, and simplify troubleshooting.
