Measures temperature and humidity / output as a 4 ... 20 mA signal / compact

Modbus RTU interface / wall mounting

The thermo hygrometer is used in HVAC technology to monitor humidity and temperature. The measured values are output by the thermo hygrometer as a standard signal 4 ... 20 mA. In this compact thermo hygrometer, air humidity and temperature are precisely determined using a semiconductor component. For commissioning, the thermo hygrometer is supplied via a DC voltage. The measured variables are output via a two-wire line. All connections are made via screw contacts in the waterproof IP 65 housing. In addition to the output of the measurement signal as a 4 ... 20 mA signal, the measurement values can be output via the RS485 interface. This function is particularly useful if several measuring points are to be linked to one another during your home surveillance.

RS485 / USB signal converter PCE-PD10

The USB / RS485 signal converter PCE-PD10 is required to connect different Modbus devices to the PC. The RS485 / USB signal converter allows parameters of Modbus devices to be changed via software (compatibility note). Up to 32 Modbus devices can be connected to a PC via the signal converter. The two interfaces of the signal converter are galvanically separated from each other, so that a destruction of the PCs or the Modbus devices is excluded.
