3.3.2 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
DC
. If an
external voltage (5 ~ 40 V
DC
) 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.

3.3.3 Channel-Freeze Function
The PCIE-1752 provides a digital input channel (CH_FRZ_IN) to enable
the channel-freeze function. The channel-freeze function acts when the
pin CH_FRZ_IN is activated. Moreover, you can setup the input mode of
channel-freeze function input channel CH_FRZ_IN as dry contact input
mode or wet contact input mode selected by on-board jumper JP2. The
wiring in wet contact and dry contact input mode are shown in Figures
3.4 and 3.5.
