We have a new system here at our facility that is using Mechanical Relays to control 24 VDC solenoid valves in a hydraulic system. Our relays are failing very frequently. When looking at the relays the contact does appear to be charred. And during operation I notice sparking. Do you think that the sparking is from the inductive kick back of the voltage being stored in the coil? And, if so, would a diode be the answer to increasing the life of these relays?
Or, do you think that the spark is being generated during the charging up of the solenoid valve coil? If this is the case, I may need to use a solid state relay to solve the issue.
Please, I'd like to hear any advice you have to offer.
The relays that we are using are AB 700-HK36Z24-4.
The solenoid valves that are being controlled through these relays are located about 20 to 50 feet from the relays.
