5WG1254-3EY02 AP 254/02 A
AP 254/02 Dual sensor for brightness measurement, temperature measurement, sun
protection control, lighting control
• Brightness measurement, temperature measurement, sun protection control, lighting control
• For the detection and transmission of brightness and temperature
- Temperature measuring range -25 °C...+55 °C
- Brightness measuring range 1 Lux...100 kLux
- Horizontal sensing angle -60°...+60°, vertical -35°...+66.5°
• For the control of switch, dimming and shutter/blind actuators, depending on the ambient luminosity
and/or ambient temperature
• One sun protection channel for the automatic control of sun protection equipment, with
- Starting and stopping of automation by means of an object or a dusk threshold
- Up to three brightness thresholds for determining the height and position of the shutters/blinds or
roller shutters
- Optional teach-in of dusk thresholds and brightness thresholds by means of a teach-in facility
- Blocking object for the temporary deactivation of the sun protection channel function
• Up to four universal channels for the control of switch, dimming and shutter/blind actuators,
depending on ambient luminosity and/or temperature. Optionally available with:
- Threshold switches for brightness
- Threshold switches for temperature
- Threshold switches with logical combination of brightness and temperature
- Optional teach-in of brightness threshold for each universal channel by means of an associated
teach-in facility
- Deactivation option for each universal channel by means of an associated blocking object (1 bit)
- Optional second object for transmission of a second telegram on fulllment of threshold conditions
