CO2TRH-W-D m. Touchfarbdisplay
Art. no. 103682
CO2, temperature and humidity transducers. 3 x 0 – 10 V, relay, Mod/BAC output.
3–way transmitter. For indoor installation. Large,
illuminated color touchscreen (36x49 mm).
Configurable via the display. Sensor metrics and
measuring ranges: CO2: 0 – 2,000 ppm (0 – 10 V,
Mod, BAC) Temperature: 0 – 50 °C (0 – 10 V, Mod,
BAC) Relative humidity: 0–100% (0 – 10 V, Mod,
BAC) Display configurable as alternating or
fixed. Graph for all 3 sensor metrics. 2 limit
indications can be programmed per sensor metric.
Color changes to yellow or red if the limit is
exceeded. Modbus + BACnet interface as a standard
feature. Relay output for CO2 (switching relay,
loadable from 1 mA/5 V to 1 A/50 V AC/24 V DC),
activated at 1,000 ppm CO2, hysteresis 100 ppm
(configurable). For demand-based control of
ventilation systems. The CO2 measuring principle
is based on non-dispersive infrared technology
with automatic self-calibration. 5 year service
intervals. Power supply: 24V AC/DC ± -20% Power
consumption < 0.6 W m. Display, max. 2 W peak.
Permissible ambient conditions 0 – 50°C, 0 –
95%rH. Non-condensing. Perm. storage temp. -30 –
+70°C. Housing for vertical wall mounting, white.
Protection class: IP 20. Screw terminals max. 1.5
mm². Dimensions: approx. 83x122x23 mm (W x H x
D).
