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 24VDCRS232/RS485 serial interface4 optoisolated digital inputs4 optoisolated digital outputs2 channels frequency
