RL2/A-UI - The mixed gas sensor (VOC) with LED display measures the air quality in the range of 0...100% referring to the calibration gas. For further processing it provides a linear output signal 0-10 V, 0-20 mA, 4-20 mA and a change-over contact. The normal air quality of the enviroment can be defined for standard by manual calibration on the device (zero point adjustment). The air quality sensor runs in regular intervals an automatic calibration procedure, therefore long-term drifts and deterioration by operation can be completely eliminated.
| Measurement range VOC: | 0-100% (good / bad air quality, referring to the calibration gas) |
| Accuracy: | ±15% FS |
| Long term stability: | < 15% FS/year at norm load |
| Sensor: | metal oxide VOC-sensor |
| Response time (t90): | max. 60 s |
| Sensor protection: | mounted inside housing |
| 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 4-20 mA: | 3-wire connection, max. RLoad(Ohm) = (+Ub - 15 V) / 0,02 A |
| Alarm output: | 1 x potential-free change-over contact, 48 V, 1 A |
| Switching Hysteresis Relay: | 2% FS (without Display), 0,5...5% FS adjustable (with Display) |
| Electrical connection: | screw terminals max. 1,5 mm² |
| Equipment: | LED display: 1-3 green (good), 4-7 yellow (average), 8-10 red (bad) |
| Automatic calibration: | The automatic VOC calibration takes place every 7 days, this compensates for any drifts and achieves excellent long-term stability. To ensure this function, the device must be supplied with power for at least 7 days without interruption and ventilated with fresh air once for approx. 10 minutes within this period. The automatic calibration can be deactivated if necessary and performed manually. |
| Running-in time: | 1 h |
| 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. |
| Cable gland: | on the back or housing side (predetermined breaking point) |
| Housing: | ABS polyman, colour signal white like RAL 9003 |
| 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 |
| Manual calibration: | The manual VOC calibration of the output signal to 1V (zero point) is started by pressing the button on the circuit board (hold down for approx. 5 seconds until the LED flashes). Before that, continuous operation of min. 2 hours with air defined as normal air quality. The LED is deactivated after successful calibration. |
| Storage temperature: | -20...+50°C |
| Installation: | on-wall or on flush-mounted box |
| Approvals: |
CE, EAC, RoHS |
