GuardPLC 1600 Safety Controllers

Bulletin 1753 GuardPLC™ 1600 Controllers are among the fastest safety PLCs in the industry. They provide 10 milliseconds throughput and exceptionally high mean-time between failures, ensuring system safety and reliability. These cost-effective, packaged controllers are ideal for smaller applications and provide integrated digital I/O points.

GuardPLC 1800 Safety Controllers

Bulletin 1753 GuardPLC™ 1800 Controllers have the same features as the GuardPLC 1600 controller.These packaged controllers include analog inputs and high-speed counter inputs for specialized applications such as emergency shutdown, flame control and amusement-park ride control.

GuardPLC Safety I/O

GuardPLC™ controllers integrate with 1753 GuardPLC I/O modules.

RSLogix Guard PLUS! Software

Bulletin 1753 RSLogix™ Guard PLUS programming software helps you develop and test programs for all of your GuardPLC systems. This software is project-based, so you can store programs for multiple controllers in one project. RSLogix Guard PLUS is based on graphical function blocks and supports safety Certified Function Blocks.

GuardPLC OPC Server Software

Bulletin 1753 GuardPLC™ OPC Server software lets a Windows®-based PC read data from—and write data to—GuardPLC controllers across the GuardPLC Ethernet network.
