5.11 Digital I/O Function (Digital Port)

The IT6000C series power supply supports digital I/O function. The user can
realize logic control over high and low level input or output by related configura-
tions in the system menu, namely general digital signal I/O function. In addition
to general digital I/O functions, this series can be customized to meet different
special needs through different pin wirings. For example, you can connect a pin
to an external instrument, and set a fixed pulse or level signal for the external in-
strument. Once the external instrument fails, output this pulse or level signal.
After the instrument identifies this signal, it controls whether the power supply
output is reduced to 0 or whether the [On/Off] is switched off based on related
settings.
The rear panel of the instrument has a green 8-pin terminal (For position, see

achieve different functions.
