Duct temperature humidity CO2 sensor - 24 VDC supply - 3 outputs


This is a multifunctional duct transmitter. It measures temperature, relative humidity and CO2 (carbon dioxide). The supply voltage is 24 VDC. The measured values are transmitted via three analogue outputs and via Modbus RTU communication. The output type can be selected: 0-10 VDC / 0-20 mA / 0-100 % PWM. The CO2 sensor element is replaceable. All settings can be adjusted via Modbus RTU.

Frequently asked questions:
In general, the difference is the supply voltage: -M version: The –M versions are Power over Modbus supplied with 24 VDC via an RJ45 socket. They do not feature a physical out, however, there is an output value generated and read via Modbus RTU. When combining multiple Sentera products via Modbus RTU, we advise to use –M or -F series. -F version: The –F version is supplied with 18 - 34 VDC via a terminal block and features physical outputs. The -F version of the product is not suited for 3-wire connection. It has separate grounds for power supply and analogue output. Connecting both grounds together might result in incorrect measurements. Minimum 4 wires are required to connect -F type sensors. When combining multiple Sentera products via Modbus RTU, we advise to use –M or -F series. -H version: The –H version is a combination of –M and –F series. They can be supplied via Power over Modbus (24 VDC via an RJ45 socket) or via the terminal block, whichever the customer prefers. The –H series also features physical outputs via the terminal blocks. -G version: The –G version features 18 – 34 VDC or 15 – 24 VAC. The -G version is intended for 3-wire connection and features a ‘common ground’. This means that the ground of the analogue output is internally connected with the ground of the power supply. In case a Sentera sensor will be connected to other, non-Sentera branded products, we advise to use –G series.
