Relay that switches the wiper drive motor in a TrojanUVSwift ultraviolet reactor. The controller calls for a wipe at a preset interval and this relay passes motor current for the duration of the stroke, so it switches an inductive load many times a day for the life of the system and is one of the wear items in the wiper circuit. A wiper that no longer moves while the controller still reports a wipe cycle is worth checking here as well as at the motor. Contact us if you are unsure whether this part fits your UV system.
