The electronic speed monitor relay EDO is used in connection witha pulse sensor to monitor the rotational speed and standstill ofdrives.Pulse sensors according to NAMUR EN 50227 as well as 3-wiresensorscan be connected to the EDO relay. The pulse outputis fed to the speed monitor relay where the pulse frequency iscompared with the frequency set by the control of the relay. Whenthe input frequency passes the set frequency the internal outputrelay is switched.Warning or control equipment can be connected to this outputrelay and operate when the speed either increases or decreasesfrom the setpoint.The new multi-layer contact of the output relay improves the trueoperation 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 themonitored drive by adjusting the start-up potentiometer to thetime taken for the drive to reach operating speed.
