Our MSR100 Single-function Safety Relays support a wide variety of input devices and output configurations. These relays are ideal for relatively small safety applications and single zone control and available in electromechanical version, or solid-state models for applications involving high cycle rates. Rockwell Automation announces that as of December 2019, a small number of legacy safety relays in the MSR portfolio will be discontinued and will no longer be for sale. Customers are encouraged to migrate to safety relay products in both our MSR and GSR families.
