I work with PVs.
I have an NI USB 6509, a USB powered digital driver box for use with LabView, it basically allows me to control 96 channels of digital on / off signals.
Each channel can hold up to 24mA at 5V.
The only relays I could find that trigger at such low voltages / currents are latching relays. This is because, I assume, they use a magnet on their actuator. I am using a TQ-2-L-5V.
I hook it up to the following circuit and for the life of me cannot get it working...
**broken link removed**
From the site, I think the above circuit is made for 12V but I have run many simulations and cannot get it working at any voltage properly.
Could anyone please help me with the above circuit or suggest another that I could use with the pile of latching relays I bought?
