3.3.4 Channel-Freeze Function

The PCIE-1756 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.
