Used Safety Relays

This category is for used safety relays. Compare the supply voltage, required safety function, single/dual-channel and OSSD input compatibility, safety outputs and reset mode. Confirm support for emergency stop, safety gate or light curtain monitoring against the full model number.

Check manual, automatic and monitored start/reset options, any output delay and external device monitoring (EDM). The connected safety switches and downstream contactors must meet the model's connection requirements. Distinguish safety outputs from auxiliary status outputs. Similar housings or matching contact counts do not establish interchangeability.

Verify any PL/SIL declaration and service-life limit against the documentation and application conditions for the exact model. Technical background is available under what a safety relay is; new control accessories are listed under emergency stop buttons.

To buy, browse the product listings in this category. Your seller is the store identified on the product page. Confirm price, availability, delivery, specifications and condition with that store; listings should not all be treated as DERELL's own inventory.

Distinguish between used, unused, boxed, repaired, faulty and parts-only items. Operating/repair history, known faults and missing accessories must be disclosed. Where tests have been performed, state the conditions for channel, reset, feedback and output checks. Power-up or an illuminated LED alone must not be presented as a safety function test. Test coverage, any warranty and declarations of standards compliance depend on the store's product description. A boxed or unused item does not automatically come with a warranty. Product testing does not replace validation of the machine's safety function.

To offer a safety relay for sale, email the brand, full model number, quantity, working or faulty condition, clear photographs of the unit and its nameplate, and your asking price to otomasyonavm@gmail.com. Include operating/repair history and configuration details if known. We do not purchase products without an invoice. A submission is neither a commitment to buy nor an automatic listing service.

Listings are updated approximately every 10 days. A sold item may remain visible briefly, so confirm availability with the selling store before ordering.
