Description
The Rockwell Automation 440R series, including the MSR127T, MSR127TP, and MSR126 models, are high-performance safety relays designed for industrial automation applications. These relays are part of the Guardmaster Minotaur family, providing reliable monitoring and control for safety circuits. They are engineered to detect faults in safety systems and de-energize outputs to prevent hazardous machine operation. With features like cross-fault monitoring, automatic/manual reset options, and compact DIN rail mounting, these relays ensure compliance with safety standards such as EN ISO 13849-1 and IEC 61508.
