Digital inputs RI
Basic description¶
The TGZ servo amplifier has eight galvanically isolated fast digital inputs integrated on the X8 connector in the ruggedized (RI) version. All of them are standard, passive, with a nominal input level of +24V. Its operation does not require the VCCIO supply, however GNDIO must be always connected, as the inputs are galvanically isolated. All digital inputs DI 1-8 have built-in reverse polarity protection (down to -70V) and overvoltage protection (above 30V).

Use with Hall sensors¶
We recommend using voltage translation module TGHall for use with Hall sensors, which you can also order.
