case, a minimum of 4 power pins should be used. Nine power pins are provided
to allow for more wire connections to decrease the voltage drop across the power
supply wires. If you experience an excessive voltage drop, make connections to
additional power pins (to a maximum of 9).
The ground connection should connect to the power supply directly, not to the
ground connection of the load. This will isolate the board from any voltage drop
across the load ground wires.
The above specs apply only to the output channels on the
DIO board. See Chapter 8 for specs on the digital output channels
on the SIO board. See Chapter 5 for specs on the digital output
channels on the CIP.
