Guardmaster Minotaur MSR57P safe-speed monitoring relay
Rockwell Automation says the Allen-Bradley Guardmaster Minotaur MSR57P marks a major advancement in safety relays—a device that allows personnel to enter hazardous areas while machines are in motion. The device supports numerous input devices—such as E-stops, light curtains, enabling switches and interlock switches—that detect demands on the safety system and initiate a stop request of the motion. It also monitors personnel in hazardous areas while machines are in a safe-speed condition. Users can configure the safety relay with either Allen-Bradley DriveExplorer software or a human interface module (HIM device), using a variety of parameters to help meet specific application requirements, including safe direction, safe limited speed, and safe maximum speed with door control and monitoring. For example, the Guardmaster MSR57P relay can help increase productivity by unlocking doors automatically when the speed of the machine is below a safe speed limit or zero speed is detected. It is designed for easier integration, flexibility and performance, in new and existing installations.
