up to a maximum of 2,000 V
DC
ESD (Electrostatic Discharge) protection
for input channels. Even with an input voltage rising up to 70 V
DC
, the
input channels of PCI-1754/1756 can still manage to work properly
albeit only for a short period of time.
Wide Input/Output Range (PCI-1752/1754/1756)
The PCI-1754/1756 has a wide range of input voltage from 10 to 50 V
DC
,
and it is suitable for most industrial applications with 12 V
DC
, 24 V
DC
and 48 V
DC
input voltage. The PCI-1752/1756 also features a wide
output voltage range from 5 to 40 V
DC
, suitable for most industrial
applications with 12 V
DC
/ 24 V
DC
output voltage. In the mean time, we
are also ready to serve your special needs for specific input/output
voltage range. Do not hesitate to ask us about tailoring our standard
products to meet your specifications. All these merits make PCI-1752/
1754/1756 the best choice for industrial applications.
Board ID Setting (PCI-1752/1754/1756)
The PCI-1752/1754/1756 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 PCI-1752/1754/1756 cards. With correct
Board ID settings, you can easily identify and access each card during
hardware configuration and software programming.
Channel-Freeze Function (PCI-1752/1756)
The PCI-1752/1756 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. Moreover, you can enable this function through
software as it is useful in software simulation and testing program.
Reset Protection (PCI-1752/1756)
When the system has undergone a hot reset (i.e. without turning off
the system power), the PCI-1752/1756 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.
