Ambient light sensor LDF+ active

optical4-20 mA0-10 V

Ceiling-mounted sensor used for the measurement of brightness or ambient light levels. Depending on the prism (straight or diagonal), light levels can be detected reliably and selectively in living rooms, offices and work spaces. The sensor is adapted to the spectral sensitivity of human eyes and contributes to a demand-based efficient control of light and sunblinds/shading systems. The remote sensor can be connected to the enclosure with a conventional RJ45 cable, allowing for an easy installation even in hardly accessible locations. If two sensors are used, the average, minimum or maximal value of both brightness signals can be provided in addtion to the independent measurements of each sensor (configurable via Thermokon USEapp). • Application/type : Ceiling sensor, Room sensor • Purpose : Measure values • Measured values : luminosity • Interface : Active, 0..5 V, 0..10 V, 4..20 mA, Switch contact • Configuration : USEapp, uConfig, jumper, DIP switches • Sensor : ambient light sensor with precise optical filtering appropriate to the human eye • Output voltage : 0..10 V or 0..5 V, 2x 0..10 V or 0..5 V, adjustable via jumper, live-zero configuration via app or uConfig, min. load 10 kΩ • Output current : 4..20 mA, 2x 4..20 mA, max. load 500 Ω • Output switch contact : 2x floating contact NO for 24 V ~ or 24 V = / 3 A • Operating range temperature (°C) : -25..+65 • Operating range humidity : max. 85% rH non-condensing • Measuring range light : selectable from 6 ranges 0..200 lux | 0..1000 lux | 0..2 klux | 0..10 klux | 0..20 klux | 0..50 klux, optionally configurable
