Inputs can be set for short runs (up to 30 m (98 ft)) or long runs (up to 100 m (328 ft)) with end-of-line resistor supervision, which lets the module watch magnetic contacts and detectors with a tamper-aware level of safety that plain inputs do not offer.\u003c\/p\u003e\n\u003cp\u003eIt does more than switching: all 4 inputs can be reconfigured as analog NTC probe inputs to publish temperatures or run a complete 2-stage PI thermostat, two inputs can host plug-in SM03E01ACC (CO₂ + temperature) or SM03E02ACC (VOC\/eCO₂ + temperature) smart sensors, and 10 logic blocks plus a pulse counter are available for metering and interlock tasks. Typical uses are hotel rooms, offices and retrofits where existing low-voltage wiring already terminates in the panel.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e4 dry-contact inputs for pushbuttons, switches, sensors; functions for on\/off, dimming, shutters, scenes and sequences\u003c\/li\u003e\n\u003cli\u003eLong-distance mode up to 100 m (328 ft) with 1.8 kΩ (1\/8 W) EOL resistor line supervision; short-distance mode up to 30 m (98 ft)\u003c\/li\u003e\n\u003cli\u003ePulse counter on inputs configured as short-distance digital\u003c\/li\u003e\n\u003cli\u003eNTC analog mode on all 4 inputs: temperature to bus or a full 2-stage PI thermostat module for heating\/cooling, valves and 2\/4-pipe fan coils\u003c\/li\u003e\n\u003cli\u003eTwo inputs accept plug-in smart sensors SM03E01ACC (temperature + CO₂ 10–1000 ppm) or SM03E02ACC (temperature + VOC \/ eCO₂)\u003c\/li\u003e\n\u003cli\u003e10 logic blocks with logical, threshold, algebraic and conditional operators; predefined algorithms for proportional control and dew point\u003c\/li\u003e\n\u003cli\u003ePer-input status LED on the front panel\u003c\/li\u003e\n\u003cli\u003eBus-powered, ≤ 15 mA; 4-module PC-GF housing; 250 group addresses \/ 250 associations\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≤ 15 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs (digital mode)\u003c\/td\u003e\n\u003ctd\u003e4 dry-contact inputs; scanning voltage 20 V DC; long cable test current 6 mA, short cable 1 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax cable length\u003c\/td\u003e\n\u003ctd\u003eLong distance 100 m (328 ft); short distance 30 m (98 ft) (twisted)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEOL supervision\u003c\/td\u003e\n\u003ctd\u003e1.8 kΩ, 1\/8 W end-of-line resistor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInputs (analog mode)\u003c\/td\u003e\n\u003ctd\u003eNTC probes TS01A01ACC (-20 to +100 °C) or TS01B01ACC (-50 to +60 °C) on all 4 inputs; max cable 30 m (98 ft) twisted\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSmart sensor inputs\u003c\/td\u003e\n\u003ctd\u003e2, for SM03E01ACC \/ SM03E02ACC plug-in sensors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLogic blocks\u003c\/td\u003e\n\u003ctd\u003e10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGroup addresses \/ associations\u003c\/td\u003e\n\u003ctd\u003e250 \/ 250\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eDIN rail, 4 modules; LV distribution switchboard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnclosure\u003c\/td\u003e\n\u003ctd\u003ePC-GF, IP20 (EN 60529)\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, indoor use\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandards\u003c\/td\u003e\n\u003ctd\u003eEN 63044-3; EN 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\u003eBI0xF01KNX binary input application\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (net)\u003c\/td\u003e\n\u003ctd\u003e0.14 kg (0.31 lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer part no. \/ GTIN\u003c\/td\u003e\n\u003ctd\u003eBI04F01KNX \/ 8054144522272\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eRelated Products\u003c\/h3\u003e\n\u003cp\u003eFamily: BI08F01KNX (8 inputs), BI16F01KNX (16 inputs, mains-assisted) and BI08H01KNX (8 x 100–250 V inputs).
