Rockwell Automation Releases New SIL 3 Safety Controller Line with Advanced Software Capabilities

July 23, 2020 by Alessandro Mascellino

Rockwell Automation announced a new family of safety controllers last week, with key features to increase performance.

The new Allen-Bradley Compact GuardLogix 5380 SIL 3 allows engineers to scale applications up to and including SIL 3/PLe performance with 1oo2 architecture. The controllers are designed to help companies build smarter, simpler, and better-performing machines.

The Compact GuardLogix 5380 SIL 3 Controllers

The new SIL 3 controllers are an addition to Rockwell Automation’s GuardLogix 5380 series. The devices can achieve up to SIL 2/PLd with 1oo1 architecture or up to SIL 3/PLe with 1oo2 architecture and offer standard memory options from 0.6 to 10 MB and safety memory options from 0.3 to 5 MB. In terms of connectivity, the GuardLogix 5380 SIL controllers 3 have a gigabit embedded Ethernet port that enables CIP safety connections, I/O, and safety devices.

They also support communication options for up to 180 EtherNet and IP nodes, 31 local Compact 5000 I/O modules, and integrated motion on EtherNet/IP up to 32 axes The new range features an extensive series of certifications, including ATEX, CE, and c-UL-us, among others.


Built with High Processing Power

The technical capabilities of the GuardLogix 5380 SIL 3 make the devices a flexible option to design safety control systems based on an application’s specific safety assessment, thus reducing design and acquisition costs. The high processing power in the controller also means the machine can achieve both faster reaction times and shorter safe distances. This translates into the development of smaller machines, saving floor space and increasing operator efficiencies.

Utilizing a single controller for both standard and safety control reduces the system’s cost, complexity, and cabinet size, also enabling engineers to mix and match standard and safety I/O in the same chassis.


The Studio 5000 Logix Designer Software
Like the other products in the Compact GuardLogix 5380 Series, the SIL 3 controllers work through Rockwell’ Studio 5000 Logix Designer software. The tool is specifically intended to enable engineers to design and configure CompactLogix systems using 5380 controllers. The controllers and modules selected, together with network configuration details, determine what additional software packages are needed to configure and program a specific system.
