FAQ

What factors should I consider when purchasing a relay?

Consider the relay's voltage and current ratings, the type of relay (electromagnetic, solid-state, etc.), and the environmental conditions it will operate in. Compatibility with your existing system is also crucial.

How can I ensure my relay is shipped safely?

Ensure the relay is packed in anti-static packaging and cushioned to prevent damage during transit. Use a reliable shipping service that handles fragile electronic components.

What maintenance is required for relays?

Regular maintenance includes checking for signs of wear or damage, ensuring connections are secure, and occasionally cleaning contact points if applicable. Follow the manufacturer's guidelines for specific maintenance procedures.
