This connector provides means for eight general-purpose inputs and eight general-purpose outputs. Inputs and
outputs may be configured to accept or provide either +5V or +24V signals. Outputs can be made sourcing
with an IC (U13 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.
