The IoT meter has an adjustable measuring range of 0… 600 V AC/DC and can therefore measure a wide variety of voltages. For example, it is possible to connect the IoT meter to the supply line in order to monitor the applied voltage. In addition to voltage measurement, the IoT meter can also measure the current directly with a maximum adjustable measuring range of 0 … 5 A AC/DC. A current transformer can be connected to the IoT meter to expand the current range. The measured value is then converted by the IoT meter into a standardized analog 4 … 20 mA or 0 … 10 V signal. Thus the IoT meter is the ideal extension of a process control.
Since the input and output range can be set identically, the transmitter can be used for galvanic decoupling. The transmitter is configured directly via the keypad. This means that no additional cable or software is required for the settings of the signal converter. The transmitter is mounted on a DIN rail. The transmitter is operated with a voltage of 18 … 265 V AC/DC at a frequency of 45 … 65 Hz.
