Frequency reader board
The board, realized few year ago, permits to read two frequency channels, with a range that can be set via the RS232 (or RS485) serial interface from a few Hertz up to a few hundred of Hertz, and compare them to activate the relative digital and analog outputs, also based on the selected operating mode.
Here are the characteristics:
- Power supply 24VDC
- RS232/RS485 serial interface
- 4 optoisolated digital inputs
- 4 optoisolated digital outputs
- 2 channels frequency reading
- 2 analogs 4-20 mA outputs
- 2 analogs 0-10V outputs
- Dip-switch to select the operating mode
