Sentry Safety Relays

ABB Sentry Safety Relays are designed as both a simple and advanced safety solution, available in four styles that handle various types of safety functions. These relays feature quick connection and replacement and an intuitive push-in connection, requiring no additional tools for installation. Sentry relays offer a vibration-resistant and maintenance-free connection and easily reach the PLe/SIL3 safety level. Utilized as a signal stop condition for control, ABB Sentry Safety Relays can be used to monitor safety devices, including emergency stops, gate switches, and light curtains.
