At 52 x 28 mm it fits behind a switch plate or in a ceiling box, which makes it the natural choice for retrofits and for hotel rooms where a few local loads and contacts must join the bus without running cable back to the panel.\u003c\/p\u003e\n\u003cp\u003eTwo inputs are digital, one is digital\/analog and one is digital\/analog\/smart-sensor: NTC probes (TS01A01ACC, TS01B01ACC, TS01D01ACC) feed a complete 2-stage PI thermostat, and input 4 accepts the SM03E01ACC (CO₂ + temperature) or SM03E02ACC (VOC\/eCO₂ + temperature) plug-in sensors for air quality. The two 10 A relays work independently, as a shutter pair, as a servomotor pair or with logic interlock. The iBeacon\/Eddystone-compatible BLE beacon lets a guest app detect which room it is in, and the Virtual Holder logic derives reliable occupancy from a door contact plus presence sensors.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2 digital inputs + 1 digital\/analog input + 1 digital\/analog\/smart-sensor input (dry contacts, SELV)\u003c\/li\u003e\n\u003cli\u003e2 bistable relay outputs, 10 A cos φ 1 at 230 V AC: independent loads, one shutter\/blind channel, servomotor pair or interlocked\u003c\/li\u003e\n\u003cli\u003eInputs 3 and 4 accept NTC probes TS01A01ACC \/ TS01B01ACC \/ TS01D01ACC; complete 2-stage PI thermostat for heating, cooling, valves and 2\/4-pipe fan coils\u003c\/li\u003e\n\u003cli\u003eInput 4 hosts plug-in smart sensors SM03E01ACC (temperature + CO₂) or SM03E02ACC (temperature + VOC\/eCO₂)\u003c\/li\u003e\n\u003cli\u003eKNX Data Secure communication configurable in ETS\u003c\/li\u003e\n\u003cli\u003eIntegrated BLE beacon (iBeacon and Eddystone formats) with adjustable transmission interval and signal strength\u003c\/li\u003e\n\u003cli\u003e12 logic blocks with logical, threshold, algebraic and conditional operators; proportional-control and dew-point algorithms\u003c\/li\u003e\n\u003cli\u003eVirtual Holder logic for hotel-room presence detection\u003c\/li\u003e\n\u003cli\u003eWired AWG26 input leads (90 mm), screw terminals for outputs; nylon housing, 52 x 28 mm, approx. 50 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower supply\u003c\/td\u003e\n\u003ctd\u003eVia KNX bus, 21–32 V DC (SELV)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent consumption\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 10 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs (digital mode)\u003c\/td\u003e\n\u003ctd\u003eDry contacts; scanning voltage 3.3 V DC (internally generated); max cable 10 m (33 ft) twisted; AWG26 leads 90 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs (analog mode)\u003c\/td\u003e\n\u003ctd\u003eNTC TS01A01ACC (-20 to +100 °C), TS01B01ACC (-50 to +60 °C), TS01D01ACC (-5 to +45 °C); max cable 30 m (98 ft) twisted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutputs\u003c\/td\u003e\n\u003ctd\u003e2 relays, 10 A cos φ 1 at 230 V AC; resistive 10 A, incandescent 6 A, inductive (motor) 3 A; check LED driver inrush\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWireless\u003c\/td\u003e\n\u003ctd\u003eBLE beacon, iBeacon \/ Eddystone compatible\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLogic blocks\u003c\/td\u003e\n\u003ctd\u003e12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGroup addresses \/ associations\u003c\/td\u003e\n\u003ctd\u003e264 \/ 308\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eFlush-mount wall or ceiling box\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnclosure\u003c\/td\u003e\n\u003ctd\u003eNylon, IP20 (EN 60529); protection class III; overvoltage class III; pollution degree 2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eØ 52 x 28 mm (2.05 x 1.10 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating temperature\u003c\/td\u003e\n\u003ctd\u003e-5 °C to +45 °C (23 °F to 113 °F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage temperature\u003c\/td\u003e\n\u003ctd\u003e-20 °C to +55 °C (-4 °F to 131 °F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelative humidity\u003c\/td\u003e\n\u003ctd\u003emax 90 % non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandards\u003c\/td\u003e\n\u003ctd\u003eEN 63044-5-1 \/ EN 63044-5-2; EN 50491-2; LVD 2014\/35\/EU; EMC 2014\/30\/EU\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eKNX certified; CE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eETS application\u003c\/td\u003e\n\u003ctd\u003eIO42E01KNX application with KNX Data Secure\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (net)\u003c\/td\u003e\n\u003ctd\u003e0.09 kg (0.20 lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer part no. \/ GTIN\u003c\/td\u003e\n\u003ctd\u003eIO42E01KNX \/ 8054144522630\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eRelated Products\u003c\/h3\u003e\n\u003cp\u003eInput-only in-wall interfaces: IO22D02KNX, IO44D02KNX \/ IO44D02KNX-S (secure), IO62D02KNX; analog\/LED in-wall module AD84C01KNX.
