3.3.3 Isolated Digital Output

Each of isolated output channels comes equipped with a MOSFET, poly-

switch (for current protection) and flywheel diode for using with induc-

tive loads which can be activated by connecting PCOM to V

. If an

external voltage (5 ~ 40 V

) is applied to an isolated output channel, the

current will flow from the external voltage source to the card. Please note

that the current through each IDO channel should not exceed 500 mA.
