Power/Ground Systems

There are three different power/ground systems on the Opto trigger board. One supplies the signals of the port A connector, another one the signals of the port B connector, and the third one the signals of the flat cable connector. There is no electrical connection between these three power/ground systems.

Each of the three power/ground systems may have a different supply voltage. The voltage range lies between 6 and 25.0 Volt. The signal voltage is defined by the supply voltage for both, input and outputs. For details on the electrical characteristics, refer to section Electrical Characteristics.
