This connector provides means for eight general-purpose inputs and eight general-purpose outputs.
Inputs and outputs may be configured to accept or provide 5V or +24V signals. Outputs can be
made sourcing with an IC (U11 to UDN2981) and jumper (E1 & E2) change. E7 controls whether the
inputs are pulled up or down internally. Outputs are rated at 100mA per channel.
