The IT0229 is a high resolution (12 bit) multipurpose datalogger with eight analog and two digital pulse inputs. The datalogger supports an additional 15 channels of input from remote sensors on an RS485 interface. It also provides a Start on Trigger input and two Alarm outputs and can be configured to accept input from a wide variety of sensors. The eight analog channels have identical characteristics. Each channel can operate in two modes, Absolute and Ratiometric. The mode of operation is determined by the probe type selected for that channel. Temperature (Thermistor), Pressure and Humidity Probes are typically Ratiometric. Voltage and Current inputs are Absolute. There is one Fast Pulse digital channel and one Slow Pulse digital channel and these can be used in two modes, Counter and Frequency. Counter mode is used for functions such as rainfall. Frequency mode is used for wind speed or flow sensors.
