El AO-RL2/A había mezclado sensor de gases (VOC) con las medidas de pantalla de LED la calidad del aire en el rango de 0... 100 refiriéndose al gas de calibración. Para la transformación posterior proporciona un lineal 0-10 V, la señal de salida 0-20 mA, 4-20 mA y un contacto. La calidad del aire normal del ambiente puede definirse para el estándar de calibración manual en el dispositivo (ajuste del punto cero). El sensor de calidad del aire ejecuta en intervalos regulares un procedimiento de calibración automática, por lo tanto deriva a largo plazo y deterioro por la operación pueden ser totalmente eliminados.

Measurement range VOC	0...100% (good / bad air quality, referring to the calibration gas)
Accuracy	±15% FS
Response time (t90)	max. 60 s (at 5% alteration)
Long term stability	< 15% FS/year at norm load
Sensor	metal oxide VOC-sensor
Sensor protection	mounted inside housing
Running-in time	1 hour
Supply voltage	24 V AC/DC (±5%)
Current consumption	max. 60 mA
Analogue output 0-10 V	3-wire connection, min. load resistance 100 kOhm
Analogue output 0/4-20 mA	3-wire connection, load resistance < 500 Ohm
Alarm output	potential-free change-over contact max. 48 V (1 A), threshold can be defined by 270° potentiometer
Equipment	LED display: 1-3 green (good), 4-7 yellow (average), 8-10 red (bad)
Electrical connection	screw terminals max. 1,5 mm²
Housing	ABS polyman, colour signal white like RAL 9003
Cable gland	at the backside of the housing
Dimensions	Housing: L 82 x W 82 x H 25 mm
Weight	ca. 70 g
Protection type	IP30
Protection class	III
Working range r.H.	0...98% r.H. in contaminant-free, non-condensing air
Working temperature	0...+50°C
Storage temperature	-20...+50°C
Initial operation	After switch-on of the device follows a self-test and the tempering, which takes ca. 1 h depending on the environmental conditions. At this time the analogue output drifts from the actual measurement value.
Automatic calibration	The automatic re-calibration of the output signal is started in the interval of 4 weeks and can be disabled. The device must be supply within this interval at least 10 minutes with fresh air.
Manual calibration	The manual calibration of the output signal to 1V (zero point) will be started by pushing the button on the circuit board (push ca. 5 s until LED is blinking). Before this it is to ensure a non-stop operating of min. 2 h on air quality which is defined as normal. After successful calibration the LED will be deactivated.
Installation	on-wall or on flush-mounted box
Approvals	CE-conformity, EAC, RoHS
