{"product_id":"arcus-sk08-ventil4","title":"SK08-Ventil4 - KNX Valve Controller for up to 4 Heating\/Cooling Actuators or Mixing Valves","description":"\u003cp\u003eThe SK08-Ventil4 is a surface-mounted KNX control unit for up to four valve actuators or mixing valves in heating and cooling systems. Each output drives a proportional valve with 0-12 VDC or a thermal actuator with 24 VDC PWM, and the built-in controller modes let it regulate zones directly from KNX setpoints.\u003c\/p\u003e\u003cp\u003eThe grey ABS housing is rated IP54\/65. The KNX side is bus powered, while the valve outputs require an auxiliary DC supply. The ETS application is available from the manufacturer on request.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e4 valve outputs: 0-12 VDC for proportional valves or 24 VDC PWM for thermal actuators\u003c\/li\u003e\n\u003cli\u003eController modes: PI with PWM or continuous output, continuous input, switching and 2-point\u003c\/li\u003e\n\u003cli\u003eIntegrated KNX bus coupler (approx. 240 mW from the bus)\u003c\/li\u003e\n\u003cli\u003eAuxiliary supply 9-32 VDC, max. 18 W, required\u003c\/li\u003e\n\u003cli\u003eSurface mount, grey ABS housing 115 x 65 x 55 mm (4.53 x 2.56 x 2.17 in), IP54\/65\u003c\/li\u003e\n\u003cli\u003eOperating temperature -5 to +45 °C (23 to 113 °F)\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\u003e65102008\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\u003eapprox. 240 mW at 24 VDC (KNX)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAuxiliary supply\u003c\/th\u003e\n\u003ctd\u003e9-32 VDC, max. 18 W (required, yellow\/white terminal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInputs \/ outputs \u0026amp; connections\u003c\/th\u003e\n\u003ctd\u003e4 valve outputs: 0-12 VDC for linear\/proportional valves or 24 VDC PWM for thermal actuators\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProtection rating\u003c\/th\u003e\n\u003ctd\u003eIP54\/65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e115 x 65 x 55 mm (4.53 x 2.56 x 2.17 in) (L x W x H)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMounting\u003c\/th\u003e\n\u003ctd\u003eSurface mount (AP)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOperating temperature\u003c\/th\u003e\n\u003ctd\u003e-5 to +45 °C (23 to 113 °F) (storage -20 to +85 °C (-4 to 185 °F))\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eDownloads\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/www.arcus-eds.de\/fileadmin\/download.arcus-eds.de\/6000_Licht_Aktoren\/6900_Ventil4\/2910_d3_SK08_Ventil4.pdf\" target=\"_blank\" rel=\"noopener\"\u003eProduct datasheet\u003c\/a\u003e\u003c\/li\u003e\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":50554327892224,"sku":"65102008","price":309.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0673\/4161\/5360\/files\/SK08-Ventil4_innen_aussen.png?v=1791428289","url":"https:\/\/www.knxsupply.com\/products\/arcus-sk08-ventil4","provider":"KNX Supply","version":"1.0","type":"link"}
