{"product_id":"american-zettler-az420-70-4whus-nsnbc01-relay","title":"American Zettler AZ420-70-4WHUS NSNBC01 Relay","description":"\u003cdiv\u003e\u003cp\u003eAZ420-70-4WHUS NSNBC01 Relay is a four-form-C (4PDT) plug-in relay from American Zettler within the AZ420 family, featuring a 24 V DC coil and four Form C contacts in a compact PC-terminal package for panel-mount or PCB mounting. The variant’s coil voltage and form factor place it in the 24 V DC coil lineup of the AZ420-70-series relays, offering multi-line switching controlled by a single coil. The plug-in design uses PC terminals, with overall dimensions around 24.9 × 19 × 30.5 mm, making it suitable for compact control panels and automation circuits that require simultaneous switching of four independent circuits. This model is part of a family that supports DPDT (2 Form C), 4PDT (4 Form C), and 6PDT (6 Form C) configurations; exact ratings and contact arrangements vary by option. Note that the AZ420 series has been discontinued in many catalogs, with replacements such as AZ8521 suggested in current notices, so availability may be limited to surplus or distributor stock. Applications typically include multi-channel control, sequencing, and centralized IO switching in industrial control panels where a single relay package manages multiple circuits, reducing wiring and panel space while preserving reliable isolation between circuits.\u003c\/p\u003e\u003c\/div\u003e","brand":"AMERICAN","offers":[{"title":"New","offer_id":46279032209642,"sku":null,"price":435.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-077.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/american-zettler-az420-70-4whus-nsnbc01-relay","provider":"GTG Hardware","version":"1.0","type":"link"}
