RBWF/LF-US Room presence detector and light sensor

Room presence detector and light sensor

Power supply 24 V AC/DC, output presence: contact 230 V / 2 A, timeout adjustable 4 s ... 16 min., light: 0..10V ~ 0..1000 lx, wall mounted, IP30


A motion and light sensor detects motions and light intensity as well as the presence of persons and it is used to recognize conditions. Applicable for the control of lighting, heating and ventilation on an as-needed basis.

  • HVAC and lighting systems - facility automation, in corridors, at workplaces, in industrial halls and in offices and business rooms

The sensor is equipped with infrared motion sensor and a light sensor. The motion sensor signal is filtered and brought to the potential-free contact. The light sensor signal is linearized and transformed into a normalized 0..10 V output signal. 

The sensors are intended for operating in a normal and chemically non-aggressive environment. They do not need any servicing or maintenance and can be mounted in any position. 

The sensors are mounted with 2 or 4 screws on a flush-mounted junction box with 55 mm in diameter or on a plain surface.

* RBWF/LF-IS light output 4..20 mA
