We have a hydraulic press that is controlled with a PLC. There are five 120V solenoids on the press that control the movement of the Ram. Between the PLC and the Solenoids are Relays, Omron G2R-2-SN relays to be exact, which are rated for 5 amps. The solenoids don't ever pull 5 amps but I am getting a lot of arcing on the contacts and eventually they fail. I have used these before on solenoids and not had a problem but there is a first time for everything. I suspect that it is do to inductance and that I need some snubbers in the circuit. I have never used these before and was wondering if someone could point me in the right direction for finding some for this application. Do they make relays with them built into the contacts? I have never seen them if they do.
Just looking for some suggestions.
Thanks.
