The Armor™ ControlLogix and Armor™ GuardLogix® controllers extend the ControlLogix platform to the 

On-Machine™ space to put industrial control closer to the application, and sometimes onto the machine itself. 

Both controllers provide 4 MB of standard memory capacity for the most demanding applications, while the Armor 

GuardLogix controller provides an additional 2 MB of safety memory. The Armor GuardLogix controller is certified 

for use in safety applications up to Safety Integrity Level (SIL) 3 and Performance Level PLe (Category 4), where the 

de-energized state is the safe state. 

Dual independent EtherNet/IP ports and Device Level Ring (DLR) capabilities provide resiliency from loss of network 

connections due to one connection failure. 

The controllers support the same environmental ratings and global certifications as ControlLogix controllers, but now 

provide Ingress Protection (IP67 and UL Type 4/4x) for dust and washdown protection.

With so many hardware functions in one device, these controllers minimize cabinet hardware, simplify wiring layouts, 

and allow for the replacement of devices without having to stop production. The controllers do not require tools or 

specialty personnel for component replacement. These features can help improve Mean Time to Repair (MTTR), 

simplify troubleshooting, and make system status readily available without having to open a cabinet or visit a control 

room.
