Question
We were using G2R General Purpose
Relay 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 is 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.
