The 2-way analog input can record a wide range of measured values (e.g. air quality, humidity, wind direction, etc.) using universal sensors (0-10VDC, 0-20mA, 4-20mA) or temperature (PT1000 sensor, 265643) and make them available for convenient electrical installation. The power is supplied via a separate 24VDC power pack (110772 or 110773, not included in delivery!!!). The 24VDC power supply is looped through twice at the analog input and is therefore available to supply the active sensors. Depending on the sensor connected, the correct setting must be made for each channel. Attention: Check the max. load and correct supply of the sensors!!! Attention: For exact measurement and display of the values using a reference measuring device, record the deviation and set the 'offset' in the MRF. The device is installed in the junction or installation box.
