We recently faced problem with 110 volts AC operated solenoid used to actuate hydraulic control valve. The fuse to the solenoid was repeatedly blowing. Upon opening the solenoid termination compartment, we found a small PCB having 6 diodes. One of the diodes had shorted causing the fuse to blow.
The solenoid nameplate shows it is an AC solenoid. However diodes seem to form rectifier circuit. Is it DC solenoid used with AC voltage?
Can I replace the solenoid with AC solenoid ( i.e. without diodes ) since voltage available is 110 V AC.
My concern is diodes form an additional component which can fail. We cannot afford failures in this application.
