Question
We were using General Purpose Relay G2R to turn a solenoid valve ON and OFF, and sparks at the contact damaged the relay after only about 3 months of use. What caused this, and what kind of countermeasure is there for it?
Answer
It's possible that a surge resulted from reverse voltage. This speeds up the deterioration of the contacts. Try inserting a surge suppressor in parallel with the load.
