Output Power Supply Current Selection
The 9 power pins for each group are connected together on the board, and the current
supplied from the output pins is drawn from these power pins. The number of power pins
used in a particular application depends on the total current supplied through that
group’s outputs.
The supply current should be limited to a maximum of one amp per power pin. Use this
limitation to select the number of power pins you need. For example, each output can
source up to 400 mA, giving a maximum total current (for a group of 8 outputs) of 3.2 A
that will be required from the power supply. In this case, a minimum of 4 power pins
should be used. A total of 9 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 the ground
connection of the load. This will isolate the module from any voltage drop across the load
ground wires.
CAUTION:
The above specs apply only to the output channels on the DIO
module. See Chapter 7 on the SIO Module for specs on the digital output
channels on that module.
