Suitable Amplifier to operate relay

Question asked by SKUP on Feb 4, 2014

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.
