ABB's Jokab Safety Sentry safety relay includes several features to ensure reduced downtime, stock, and installation time. The relay comes with time functions: an on-off delay postpones activation and deactivation of safety outputs with a preset time delay, a time bypass function activates safety outputs for maximum predefined times when safety inputs are closed, and a time reset function activates safety outputs for a maximum predefined time when the safety inputs are opened. It is configurable with a display offering a choice between preset and custom configurations that can be password protected. The display indicates internal, input/output, system, and function faults, as well as a log of the last 10 errors. To prevent msitakes, the switch to select reset function will not change the reset function when the system is operating.
