Monitor for Speed, Standstill and Direction of Rotation

These devices are designed as monitoring modules for control cabinet installation. They are used to the monitoring of machine overspeed, underspeed, direction of rotation or standstill. Versions with analog output additionally can be used for control and regulation purposes.
Special features of these devices are the very high frequency range, the fast response and the easy configuration of the speed-, direction- and standstill-detection depending of the used signal formats.
