The electronic speed monitor relay EDO is used in connection with a pulse sensor to monitor the rotational speed and standstill of drives. Pulse sensors according to NAMUR EN 50227 as well as 3-wiresensors can be connected to the EDO relay. The pulse output is fed to the speed monitor relay where the pulse frequency is compared with the frequency set by the control of the relay. When the input frequency passes the set frequency the internal output relay is switched. Warning or control equipment can be connected to this output relay and operate when the speed either increases or decreases from the setpoint. The new multi-layer contact of the output relay improves the true operation of the contact in a wide range up to 5 A and 250 V. The operation of the relay can be inhibited during start-up of the monitored drive by adjusting the start-up potentiometer to the time taken for the drive to reach operating speed.
