| This connector provides means for eight |
| ||||||||
|
| 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. |
