cnReach radios can be ordered with a digital/analog I/O port that provides the ability to connect to a wide variety of external sensors and actuators.
- Sense switch closing/openings with Digital Inputs
- Drive motor contacts or actuators with Digital Outputs
- Count low-frequency or high-frequency occurrences with Digital Inputs
- Pull-up resistor used to keep DO either normally ‘low’ or normally ‘high’
- Digital In can sink maximum 2A
The schematic below is representative and shows how the interface works.
