Its IP54\/65 surface-mount housing is suited to indoor, outdoor and damp-room installation.\u003c\/p\u003e\u003cp\u003eUse it to monitor, control and log heating and cooling circuits from a single bus device. Resolution is 0.01 °C (0.02 °F) with ±0.3 °C (±0.54 °F) accuracy, and the measuring range runs from -50 to +400 °C (-58 to 752 °F) depending on the probe used. The unit is bus powered and configured in ETS with the Arc_S8 application. Probes are ordered separately.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e8 temperature inputs for PT500 probes (not included)\u003c\/li\u003e\n\u003cli\u003eRange -50 to +400 °C (-58 to 752 °F) depending on probe; 0.01 °C (0.02 °F) resolution, ±0.3 °C (±0.54 °F) accuracy\u003c\/li\u003e\n\u003cli\u003eMonitoring, control and logging of heating and cooling circuits\u003c\/li\u003e\n\u003cli\u003eIP54\/65 surface-mount housing for indoor, outdoor and damp locations\u003c\/li\u003e\n\u003cli\u003eBus powered, 10 mA bus load; no auxiliary supply\u003c\/li\u003e\n\u003cli\u003eETS application Arc_S8 (S8-T8)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eArticle no.\u003c\/th\u003e\n\u003ctd\u003e30801500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eKNX bus voltage\u003c\/th\u003e\n\u003ctd\u003eKNX 21-32 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower consumption\u003c\/th\u003e\n\u003ctd\u003e10 mA KNX bus load\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAuxiliary supply\u003c\/th\u003e\n\u003ctd\u003eNot required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMeasuring\u003c\/th\u003e\n\u003ctd\u003e8 temperature channels for external RTD probes (not included); range -50 to +400 °C (-58 to 752 °F) depending on probe; resolution 0.01 °C (0.02 °F); accuracy ±0.3 °C (±0.54 °F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInputs \/ outputs \u0026amp; connections\u003c\/th\u003e\n\u003ctd\u003e8 x RTD temperature inputs (PT100 \/ PT500 \/ PT1000 depending on variant)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProtection rating\u003c\/th\u003e\n\u003ctd\u003eIP54\/65 (bus coupler)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMounting\u003c\/th\u003e\n\u003ctd\u003eSurface mount (AP); indoor, outdoor and damp rooms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOperating temperature\u003c\/th\u003e\n\u003ctd\u003e-25 to +80 °C (-13 to 176 °F) (storage -25 to +80 °C (-13 to 176 °F)); 0-100% r.H. non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003eApplication note:\u003c\/strong\u003e Requires up to eight external PT500 temperature probes, sold separately.\u003c\/p\u003e\u003ch3\u003eDownloads\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.arcus-eds.de\/fileadmin\/download.arcus-eds.de\/3000_S8_Spezielle_Sensorik\/3100_T8\/3110_01_e9_SK08-T8.pdf\" target=\"_blank\" rel=\"noopener\"\u003eProduct datasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.arcus-eds.de\/fileadmin\/download.arcus-eds.de\/3000_S8_Spezielle_Sensorik\/3000_S8_allgemein\/Arc_S8_knxprod.zip\" target=\"_blank\" rel=\"noopener\"\u003eETS application\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003e(CE certified; not UL\/NRTL listed — verify local code requirements before specifying in US installations)\u003c\/em\u003e\u003c\/p\u003e","brand":"ARCUS EDS","offers":[{"title":"Default Title","offer_id":50554314621184,"sku":"30801500","price":472.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/4161\/5360\/files\/3110_SK08-T8-PT500_30801500.png?v=1791427610","url":"https:\/\/www.knxsupply.com\/products\/arcus-sk08-t8-pt500","provider":"KNX Supply","version":"1.0","type":"link"}
