Safety Relays

Safety Relays check and monitor a safety system and either allow the machine to start or execute commands to stop the machine. Single-function safety relays are the most economical solution for smaller machines where a dedicated logic device is needed to complete the safety function. Modular and configurable monitoring safety relays are preferred where a large and diverse number of safeguarding devices and minimal zone control are required.

Software Configurable Safety Relay

Guardmaster 440C-CR30 Software Configurable Safety Relay

The Guardmaster® 440C-CR30 Software Configurable Safety Relay is flexible, cost-effective, and easy to use. This relay is ideal for applications requiring as many as ten dual-channel safety circuits and controlling as many as five output zones. You can configure this relay by selecting certified safety function blocks to rapidly build your applications. This relay is completely integrated with Allen-Bradley Logix controllers and can be configured using Studio 5000 Logix Designer® software or Connected Components Workbench software. The 440C-CR30 relay can share information with the control system through the optional EtherNet/IP plug in module which increases uptime and enables The Connected Enterprise.
