Sensor Inputs
Counters / Anemometers
- Three digital anemometer inputs
- Supports dry contact switch, hall effect switch, or TTL level signal
- RC low pass filter on each input (fc=159 Hz)
- Inputs pulled to 5 volts with internal 4.7k resistor
- Measures pulses falling edge to falling edge
- Pulse time (100 microsecond resolution)
- Pulse minimum time (100 microsecond resolution)
- Number of pulses since last measurement (2^16 or 0 to 65,535)
- Number of pulses total, resettable (2^32 or 0 to 4,294,967,296)
Analog
