The PCI-1754 features a robust isolation protection for applications in industrial, lab and machinery automation. The PCI-1754 can durably withstand a voltage up to 2,500 VDC, preventing your host system from any incidental harms. The PCI-1754, if connected to an external input source with surge-protection, can offerup to a maximum of 2,000 VDC ESD (Electrostatic Discharge) protection for input channels. Even with an input voltage rising up to 70 VDC, the input channels of PCI-1754 can still manage to work properly albeit only for a short period of time.
The PCI-1754 has a wide range of input voltage from 10 to 50 VDC, and it is suitable for most industrial applications with 12 VDC, 24 VDC and 48 VDC input voltage.
The PCI-1754 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-1754 cards. With correct Board ID settings, you can easily identify and access each card during hardware configuration and software programming.
The isolated digital input channels (IDI00, IDI16, IDI32 and IDI48) are connected to the interrupt circuitry. Users can disable/enable interrupt function, select trigger type or latch the port data by setting the Interrupt Control Register of the PCI-1754. When the interrupt request signals occur, then the software will service these interrupt requests by ISR. The multiple interrupt sources provide the card with more capability and flexibility.
The function enables you to latch the last data of each associated digital input channels when the interrupt occurs and you can free the latch function by clearing interrupt. We have organized every 16 bits into one group. When the Latch Port Data Function is enabled for a specific group, the values of all channel ports in this group will be latched.
