INTRODUCTION
The PCI-1756 card offers 32 isolated digital input channels as well as 32 isolated digital output channels with isolation protection up to 2,500 V DC , which makes it ideal for industrial applications where high-voltage isolation is required. In addition, all output channels are able to keep their last values after a hot system reset. Furthermore, the PCI-1756 provides Channel-Freeze function that keeps the current output status unchanged for each channel during operating process. Robust Protection It can durably withstand a voltage up to 2,500 V DC , preventing your host system from any incidental harms.The PCI-1756 can offer up to a maximum of 2,000 V DC ESD protection for input channels. Even with an input voltage rising up to 70 V DC , the input channels of PCI-1756 can still manage to work properly albeit only for short period of time. Wide Input Range The PCI-1756 has a wide range of input voltage from 10 to 50 V DC . It also features a wide output voltage range from 5 to 40 V DC. Board ID The PCI-1756 has a built-in DIP Switch that helps define each card¡¦s ID when multiple PCI-1756 cards have been installed on the same PC chassis. Channel-Freeze Function The PCI-1756 provides Channel-Freeze function, which can be enabled either in dry contact or wet contact mode . When the Channel-Freeze function is enabled, the last status of each digital output channel will be safely kept for emergency use. Reset Protection Fulfills Requirement for Industrial Applications When the system has undergone a hot reset (i.e. without turning off the system power), the PCI-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.
