ABB Jokab Safety Sentry BSR models are cost effective safety relays for basic applications such as monitoring of e-stop buttons and expansion of safety outputs when no timer function is needed. Sentry SSR models are easy-to-use safety relays designed for specific applications such as 1 and 2 channel devices, OSSD devices and two-hand devices. Some of them offer an off-delay function. Sentry TSR models are safety timers with an excellent accuracy. Different timer functions are available depending on the model. Sentry TSR can be used as expansion relays with timer function. Sentry USR models are universal safety relays and the same model can be used with most safety devices. They all have a display on the front which facilitates configuration and error tracing thanks to extensive indication.
