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.

Guardmaster Safety Relays

Guardmaster® Safety Relays can monitor a broad range of safety devices in a variety of applications and can achieve most of the functions safety systems require, to help simplify purchasing and parts management. These single-function relays are designed to meet new functional safety standards, such as ISO 13849-1 or IEC 62061, and they offer key functions to simplify installation and system complexity. In addition, information gathered from the GSR intelligent safety relays via the optional EtherNet/IP Interface helps minimize unplanned downtime, increase efficiencies, and enable The Connected Enterprise.

MSR300 Series Modular Safety Relays

The Bulletin MSR300 family of expandable modular safety relays handles larger, more complicated safety systems by allowing connection of multiple input modules to a single base unit. It offers a logic configuration with multiple inputs and the control of multiple independent outputs. The system supports up to 20 diverse inputs and can control up to 3 zones, performing simple function block logic configurations through rotary switch settings as opposed to software configuration.

Software Configurable Safety Relay

The Guardmaster® 440C-CR30 Software Configurable Safety 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.
