24v relay to 24v D.C. solenoid wiring problem
Posted: Sun Aug 20, 2017 8:36 pm
I am setting up a glycol system using BCS-462, a relay board, 24v power supply and 24v dc solenoids.
I cannot get the relay to trigger the solenoid. I can activate the solenoid directly from the power supply just fine. See attached wiring photo. All grounds are wired together and tied to earth ground from the input power cord.
A voltmeter across the vcc and gnd terminals on the relay board reads 24v as expected. A +5v wire to the input 4 triggers the led as expected, as shown in photo. A voltmeter across either the normally closed and control or normally open and control on the relay outputs both show no voltage.
On close inspection of the relay board, the relays appear to list ac voltage, not dc. Is that my problem, was I sent the wrong board? Or does my wiring look off?
