Hi PriyankaJ,
You can use a DIO PCI card to control a custom relay bank. Relays controlled in this manner would likely be toggled open/closed via the digital states of the DIO card.
Here is a link to a DIO PCI card option, the NI PCI-6509:

As an alternative, you can also use a relay driver module. The NI PXI-2567 and the NI SCXI-1167 provide control for up to 64 external relays. The benefits to using a relay driver module are the following:
- High-power protection circuitry
- IVI-compliant NI-SWITCH driver software (compatible with NI Switch Executive)
- Provides up to 50 VDC or 600 mA per channel with an external supply
- Includes connector and backshell for signal connections
Here is a link to the product page for the NI PXI-2567:

Here is a link to the product page for the NI SCXI-1167:

Hope this helps! Let me know if you have additional questions!
