Comfort Climate Monitoring

The VT490/ Dual sensor is a high-quality humidity and temperature sensor. By connecting several VT490 in a CAN daisy chain you can measure temperature and humidity parameters in each location of a room or a server rack.

The Dew point is easily calculated using the temperature and humidity parameters of VT490 inside the Vutlan web interface.

CAN devices and sensors can be chained together. Up to 10-32 CAN devices can be connected in a chain.
RH accuracy is ± 3%, temperature accuracy is ± 0.4°C.

Connecting CAN sensors

You can connect multiple CAN devices to a CAN bus chain.

Each VT408 unit in the CAN bus chain adds 8 analog sensors. Each VT440 unit adds 32 or 64 dry contact inputs to the system.

An additional CAN12V-1A power supply is only required if the number of CAN devices in the CAN bus chain exceeds 12 pieces.

Systems with CAN ports:

To read data from the CAN sensors, you need a Vutlan monitoring device with one or two CAN ports.
