The relay’s dry contacts are electrically isolated from the power supply circuit of the device. Relay can be used in both low-voltage and domestic power grids. The device features two types of protection: voltage and temperature. Only a qualified electrician or installer should install Relay. It works only with Ajax radio signal range extenders and hubs.\u003c\/p\u003e\n\u003ch3\u003eAt a Glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePotential-free (dry) contacts — electrically isolated from the relay power supply\u003c\/li\u003e\n\u003cli\u003eSupply 7–24 V DC (recommended 12 V DC and 24 V DC)\u003c\/li\u003e\n\u003cli\u003ePulse or bistable; pulse duration 0.5 to 255 s\u003c\/li\u003e\n\u003cli\u003eMaximum load: 5 A at 24 V DC \/ 36 V DC and 13 A at 230 V~\u003c\/li\u003e\n\u003cli\u003eJeweller range up to 1,000 m in an open space\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eElectrical\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eActuating element: electromagnetic relay\u003c\/li\u003e\n\u003cli\u003eNumber of switchings: ≥ 200,000\u003c\/li\u003e\n\u003cli\u003eSupply voltage range: 7–24 V DC\u003c\/li\u003e\n\u003cli\u003eVoltage protection: minimum 6.5 V DC; maximum 36.5 V DC\u003c\/li\u003e\n\u003cli\u003eMaximum load current: 5 A at 24 V DC; 13 A at 230 V~\u003c\/li\u003e\n\u003cli\u003eOperating mode: pulse or bistable\u003c\/li\u003e\n\u003cli\u003ePulse duration: 0.5 to 255 s\u003c\/li\u003e\n\u003cli\u003eMaximum current protection: no\u003c\/li\u003e\n\u003cli\u003eParameter control: voltage\u003c\/li\u003e\n\u003cli\u003eEnergy consumption in standby mode: up to 1 W\u003c\/li\u003e\n\u003cli\u003eCross-sectional area of the cable: 0.75–1.5 mm² (22–14 AWG)\u003c\/li\u003e\n\u003cli\u003eIf you use inductive or capacitive load, the maximum switching current decreases\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eJeweller radio\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRadio communication protocol: Jeweller\u003c\/li\u003e\n\u003cli\u003eRadio frequency band: 866.0–866.5 \/ 868.0–868.6 \/ 868.7–869.2 \/ 905.0–926.5 \/ 915.85–926.5 \/ 921.0–922.0 MHz (depends on the sales region)\u003c\/li\u003e\n\u003cli\u003eMaximum radio signal strength: up to 25 mW\u003c\/li\u003e\n\u003cli\u003eRadio signal modulation: GFSK\u003c\/li\u003e\n\u003cli\u003eRadio signal range: 1,000 m in an open space\u003c\/li\u003e\n\u003cli\u003ePolling interval: 12–300 s (36 s by default)\u003c\/li\u003e\n\u003cli\u003eCompatibility: all Ajax hubs and radio signal range extenders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePhysical \u0026amp; Power\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProtection class: IP20\u003c\/li\u003e\n\u003cli\u003eOperating temperature: −20°C to +64°C\u003c\/li\u003e\n\u003cli\u003eMaximum temperature protection: over +65°C at the place of installation; over +85°C inside Relay\u003c\/li\u003e\n\u003cli\u003eOperating humidity: up to 85% with no condensation\u003c\/li\u003e\n\u003cli\u003eDimensions: 39 × 33 × 18 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 25 g\u003c\/li\u003e\n\u003cli\u003eService life: 10 years\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePart number: 42837.19.NC3\u003c\/p\u003e\n\u003ch3\u003eDownloads\u003c\/h3\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0745\/5909\/4953\/files\/42837.19.NC3.pdf\"\u003eSpecification Sheet (PDF)\u003c\/a\u003e\u003c\/p\u003e\n","brand":"Ajax","offers":[{"title":"Default Title","offer_id":47395261710505,"sku":"42837.19.NC3","price":110.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/5909\/4953\/files\/42837.19.NC3.webp?v=1788333233","url":"https:\/\/diyprosecurity.com\/products\/42837-19-nc3","provider":"DIY Pro Security Shop","version":"1.0","type":"link"}
