Used Control Relays

This category lists second-hand electromechanical control and interface relays for control panels and machinery. Select by coil voltage, AC/DC coil type, number of contacts, NO/NC contact configuration, switching capacity and socket compatibility. For AC coils, also confirm the operating frequency.

Evaluate contact current ratings together with load voltage and resistive/inductive load type. The pin count, relay socket wiring diagram and any polarity requirements for diode/LED-equipped coils must match. Similar housings or identical pin counts do not establish interchangeability. See what is a relay? for details.

Do not assume a standard control relay alone provides a complete emergency-stop safety function. Assess the safety relay and circuit architecture separately for safety-related applications.

To buy, review the products listed below. Your seller is the store identified on the product page. Confirm price, availability, delivery, specifications and condition with that store. Check whether the item is used, unused, repaired, faulty or sold for parts, and whether its box, socket, retaining clip and connectors are included. Known faults and missing items should be disclosed in the product description.

Ask about checks covering coil operation and release, contact switching, contact resistance and testing under load. Test status, any warranty and claims of compliance with standards are based on the selling store's product description. An unused or boxed item does not automatically come with a warranty.

To offer a control relay for sale, send the brand, full model code and coil voltage, quantity, working condition or known faults, clear product and nameplate photos, and asking price to otomasyonavm@gmail.com. We do not purchase products without an invoice. Offers are subject to review; submitting details does not guarantee a purchase.

Listings are updated approximately every 10 days. A sold item may remain visible briefly, so confirm availability before ordering. Browse other product groups in the second-hand MOD section and brands on the second-hand home page.
