Safety Relays

ABB Jokab Sentry safety relays are powerful and easy to use safety relays, suitable for all common types of safety applications. The Sentry series contains basic models for simple applications and easy output expansion, as well as highly flexible models with extremely accurate timer functions. Sentry safety relays are used in both simple and more advanced safety solutions when safety devices need to be monitored according to the requirements of functional safety standards.

Complete Sentry Range

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.

ABB Jokab Safety Sentry BSR and TSR models can be used as expansion relays, Expansion relays are used to increase the number of safe outputs of another safety relay or a safety PLC like Pluto. This is suitable in applications where several machines need to be stopped. Sentry BSR models are cost effective expansion relays that can also be used with the -24 VDC safety outputs of Pluto. They offer no timer function. Sentry TSR10 offers advanced timer functions, such as off-delay, on-delay, time bypass and time reset. The time is set via the display, from 0 to 999 seconds with an accuracy of ± 1%. Sentry TSR20 offers an off-delay function, 0.5 or 1.5 s selectable by switch. TRS20 is the +24 VDC models and TSR20M the mains voltage model (85-265 VAC/120-275 VDC). Main features include Up to PL e/SIL3; Simple expansion of Pluto safe transistor outputs; Excellent accuracy of ±1%; Advanced timer functions (TSR10); Easy selection of time by switch (TSR20 and TSR20M); Extensive LED indication & Removable terminal blocks.

Universal Safety Relays

ABB Jokab Safety Sentry USR models are universal safety relays and the same model can be used with most types of safety devices which reduces stock and saves warehouse space. Maintenance personnel also have fewer models to learn. All Sentry USR models have a display on the front for simple configuration. The display also offers extensive indication about the status and error messages for the relay. Sentry USR10 and USR22 are each suitable for monitoring emergency stop buttons, safety switches, OSSD-devices, two-hand devices and contact mats/bumpers/edges. Main features include One model for all applications; Up to PL e/SIL3; Simple configuration using display to select between preset configurations and custom configuration; Advanced timer functions 0 to 999 seconds: Precision of 0.1 second up to 100 seconds and 1 second over 100 seconds & Accuracy of ± 1%; Display with extensive status information; Multi-reset allows one reset button to reset up to 10 safety relays; Lighting and flashing of the reset button managed by the Sentry safety relay; Extensive LED indication & Removable terminal blocks.
