The Sentry series from ABB covers the entire spectrum of safety relays, from basic models for simple safety applications or for multiplying safety outputs, to highly flexible universal models with extremely precise timer functions. The series therefore covers all requirements for safety applications. Manual or automatic reset can be easily selected using a switch on the front of the relay. The new multi-reset function enables up to 10 Sentry safety relays to be reset with just one reset button. The basic BSR models are suitable for emergency stop shutdowns or for expanding safety outputs, for example. The single-function SSR models are suitable for applications such as monitoring contacts and OSSD signals or for two-hand switching. The TSR safety timers are characterized by their very high accuracy of better than 1%, and the USR universal models for all common safety applications also offer display and configuration options.
