0 V is internally connected to the ground of the target machine. 5 V
are supplied by the real-time target machine, which is capable of providing
1 A continuous current. For more information, refer to the real-time target
machine User Manual. The analog and digital ground pins are also connected to the ground of the
target machine through the I/O module. If an external sensor is supplied by the
5 V of the target, the ground of the sensor must be connected to the
0 V pin and not the I/O ground. This must be done to minimize current flow
through the I/O module and protect the I/O module in case of a short circuit.
