Selecting Power Supply
This board equips power supply (5VDC, 600mA) for driving opto-coupler. You can select to use this
internal power supply or use an external power supply for driving the opto-isolation circuits in unit of
two ports (16ch) per common.
CAUTION
-
When the internal power supply is used, the input section of this board consumes up to 51mA
current maximum and the output channel switching section consumes up to 105.6mA current
maximum. Note that the output current that can be supplied to the external device is therefore
443.4mA maximum in case you use internal power supply for all the input and output channels.
-
The both internal and external supply must not be used simultaneously. Or the supply will be
broken down.
Setting method
Jumpers JP2 - JP5 on the board are used to select the internal or external power supply.
