This relay can be used for a myriad of projects.The coil voltage,(what makes the relay work), can be used with 10-30 volts ac or dc or even 120 volts ac.This means you can control anything up to an 1/8 hp fan motor on 277volts by something with voltages as small as a residential AC thermostat. (24vac)These relays are also a great option for frequency drives for use as a start signal controller. This relay can be sent a 10vdc signal from a digital output to start a VFD. With parameters set, a speed reference isn't needed if you simply want the controlled device to run at full speed.I highly recommend this relay.
