input voltage. In the mean time, we are also ready to serve your special
needs for specific input voltage range. Do not hesitate to ask us about tai-
loring our standard products to meet your specifications. All these merits
make PCIE-1756 the best choice for industrial applications.
Wide Output Range
The PCIE-1756 also features a wide output voltage range from 5 to 40

Board ID Setting
The PCIE-1756 has a built-in DIP switch that helps define each card’s ID
when multiple cards have been installed on the same PC chassis. The
board ID setting function is very useful when users build their system
with multiple PCIE-1756 cards. With correct Board ID settings, you can
easily identify and access each card during hardware configuration and
software programming.
Channel-Freeze Function
The PCIE-1756 provides Channel-Freeze function, which can be enabled
either in dry contact or wet contact mode (selectable by the on-board
jumper). When the Channel-Freeze function is enabled, the last status of
each digital output channel will be safely kept for emergency use. More-
over, you can enable this function through software as it is useful in soft-
ware simulation and testing program.
Reset Protection
When the system has undergone a hot reset (i.e. without turning off the
system power), the PCIE-1756 can either retain outputs values of each
channel, or return to its default configuration as open status, depending
on its on-board jumper setting. This function protects the system from
wrong operations during unexpected system resets.
