Technical Data
Digital Input / Output
§
1 digital I/O channel, 1 digital output channel, 2 digital input channels
§
Inputs: clean contact to 0 V or 3.6 - 12 V DC referenced to GND
§
Outputs: switched 12 V or open-drain sinking to 0 V, both limited to 100 mA
Analogue
Input
/
Output
§
2 analogue inputs: uni-polar, 16 bit resolution, 30 V DC surge-protection
§
Input ranges: 0 - 0.1 V, 0 - 2.5 V, 0 - 5 V, 0 - 30 V
§
Internal 100 Ω sink resistors allow use of input current (0 / 4 - 20 mA).
§
1 analogue (excitation) output for energizing passive instruments (e.g. potentiometer type
wind vanes) or alternatively for sending a derived analogue signal to other equipment,
selectable as 0 - 5 V or 4 - 20 mA
Communications

Power Supply
§
External 12 V SLA, integral charger 10 - 30 V DC input, optional: solar panel
§
Lowest power mode current 7 mA
§
Overvoltage and reverse polarity protected with self-resetting fuse
§
Voltage of battery and charger input: monitored, logged, displayed, alarmed
§

Data Storage: Flash
Memory
§
Total 32 MB, of which 16 MB allocated to logged data / stored images (1,398,101 samples)
§
Typical autonomy: 2 parameters logged every 15 minutes and battery voltage logged
hourly will give almost 10 years of storage
