Rockwell Automation's Allen-Bradley Guardmaster Minotaur MSR57P Dedicated Safe-Speed Monitoring Relay

The Allen-BradleyA(R)GuardmasterA(R) MinotaurTM MSR57P dedicated safe-speed monitoring relay is afirst-of-its-kind safety relay - designed to allow personnel to enter hazardousareas while motion is present. The device supports numerous input devices suchas E-stops, light curtains, enabling switches and interlock switches, whichdetect demands on the safety system and initiate a stop request of the motion.It also monitors personnel in the hazardous area while the machine is in asafe-speed condition. Designed for easier integration, flexibility andperformance, the Guardmaster MSR57P relay monitors the speed of the motionvia one or two encoders, depending on the level of integrity required. If anencoder already is installed in the system, the Guardmaster MSR57P relaycan monitor the same signals without requiring another encoder to be installed.Users can configure the safety relay with either the Allen-BradleyDriveExplorerTM software or a human interface module (HIM device), using avariety of parameters to help meet specific application requirements, includingsafe direction, safe limited speed, and safe maximum speed with door controland monitoring. The integration of this level of functionality into such a compactsolution is unprecedented. TheGuardmaster MSR57P relay allows manufacturers to employ the most current safetystrategies by providing the ability to reduce the risk of personnel injury wellbelow tolerable levels without requiring a complete shutdown. For example, it can helpincrease productivity by unlocking doors automatically when the speed of themachine is below a safe-speed limit or zero speed is detected. TheGuardmaster MSR57P relay is ideal for new and existing installations, andis suitable for a variety of applications, including automotive and tiremanufacturing, printing machines, ski lifts and amusement rides.
