2.4.7 Isolated GPIO
There are 2 x electrically isolated inputs and 2 x isolated outputs, controlled by the host PC, as well as 12V nominal
power that may be used for powering attached GPIO devices. Note that the Ground and VIN are not isolated.
The mating connectoris the Phoenix Contact1952296, with two of these required. Pinouts and descriptions are
shown below.
