Hi, new to the forum and it has been many years since I messed with electronics. I have a small project where I want to control the opening of a solenoid valve (24V DC, 0.25A) with a 3V DC signal. I have verified that he valve amperage is 0.25A with a meter.
I thought the answer was to use a relay that triggers with 3V and allows 24V across the poles on the other side. I got a Songle SRD-03VDC-SL-C relay, which has a 3V coil and shows 10A for 250VAC, 125VAC, 30 VDC, and 28 VDC. I can hear and feel that the relay is toggling when 3V is applied across the coil, but it is clearly not completing the circuit on the other side of the relay. I have put 24V DC on that side without the solenoid valve in the circuit and used a voltmeter to check, I get no voltage flow across the poles when the 3V side is triggered / closed. I must be missing something basic here, can anyone assist?
Thanks in advance,
Barry
