TAIK ELECTRIC

Siro-MOD is an indoor air quality transmitter with a modern design. The transmitter is available with several optional air quality sensors.

The modular device can be equipped with CO₂ concentration and VOC measurements or PM measurement, temperature and humidity measurements. It offers easy installation and adjustment, several different model options and various output signals that are configurable separately for each measurement parameter.

Communication: RS485

Input: 24 VAC or VDC, ±10 %
Output voltage: 0–10 V/2–10 V / 0–5 V
Output current: 4–20 mA (optional)

Compensation function: On-site calibration of each measurement parameter (CO2, VOC, PM, rH, T) is possible

Measuring range: 

CO2     0–2000 ppm / 400–2000 ppm

TVOC   0–30.0 ppm/ 0–10000 µg/m3

PM1/PM2.5/PM10: 0–50 μg/m³ / 0–500 μg/m³

Temperature 0...50 °C

Relative humidity 0–100 %rH

Accuracy:

CO₂: ±40 ppm + 3 % of reading (typical),
additional ±60 ppm for first weeks
Relative humidity: ±2.2 % rH (typical at 20 °C, 30 % rH)
Temperature: ±0.4 °C (typical at 20 °C)
VOC: ±15 % of reading (typical)
*VOC sensor is tuned for typical IAQ Mix of 22 VOCs as defined by Mølhave et al. (1997)
PM:
0…100 μg/m³:
PM2.5: ±15 μg/m³(at 25 ⁰C ±5 ⁰C)
PM1/PM10*: ±25 μg/m³ (at 25 ⁰C ±5 ⁰C)
100…1000 μg/m³:
PM2.5: ±15 % (at 25 ⁰C ±5 ⁰C)
PM1/PM10*: ±25 % (at 25 ⁰C ±5 ⁰C)
*PM1 and PM10 values are calculated from PM2.5 measurement reading with the default particle distribution.
