Product Details

ZSS-I is a self-contained device used to detect and send output alarms for machinery under speed or zero-speed conditions, as well as early jamming detection. The early detection of the under speed condition is useful in reducing downtime due to jamming or transmission failure, especially in the cases of medium and large motors.The zero-speed condition is used extensively for safety interlocking applications, including: conveyors, pumps, mixers, centrifugal separators, elevators, saws, and crushers.

Linear 25 Turn potentiometer for adjusting the speed threshold
Built-in fixed power-up delay to overcome start-up inertia
Reverse polarity protection for input supply and current limited open collector PNP output
