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 (U7 to UDN2981) and jumper (E1 and E2) change. E7 controls whether the inputs are pulled up or down
internally. Outputs are rated at 100mA per channel.
