Suitable Amplifier to operate relay

Hello,

I want to use NI DAQ 6009 device which can produce 2 - 3.5 mA  digital output driving current through each channel and I want to operate 4 SPDT and 2 DPDT relays (5V DC) which requires 70 - 80 mA input current each by this DAQ. Therefore I need to use amplifier circuit between DAQ output and relay input so that I could operate the relay. Kindly suggest appropriate relays and amplifier for this application.

Herewith I have attached datasheet of NI 6009 DAQ.

Thanks

  • Hi Skup,

    Thank you for considering ADI products for your applications You can use these amplifiers to drive your relays: AD8591AD8531 and  AD8000.Make sure to adjust the supply voltage of the amplifier to compensate for the output headroom of the device.

    With regards to the relay, we do not have this product and therefore I can not give you recommendation on this. But you can actually search this on digikey and the site will give you a lot options that may suits to your application.

    I hope this helps!

    Best regards,
