Dear All,
I want to connect MOVs (Mattel Oxide Varistor)with parallel of coil of each relay (220VAC) which are energizing through PLC out put Relay card for providing protection to the output card relays contacts against high voltage spikes occur when relays de-energize. But I haven’t experienced ever before.
Please help me for selecting the proper MOV.
