Why doesn't the songle sdr 12vdc sl-c relay work?

Question

Circuit design

I connected the songle sdr 12vdc sl-c relay to adruino. Ground and 5 volts from it to the relay, pin in was connected to the adruino digital pin. high level . At the same time, both the red and green lights are on on the relay, the relay does not click, the tape does not light, when low is applied to the control leg, the green lamp does not light and nothing happens either. if you connect + tapes to the no connector, then it normally lights up, which is necessary for switching.

Answer 1

Take more accurate photos from both sides and then you will get a more accurate answer.
Presumably,
"input DC+" - 12v
"signal" - control 5v
"input DC-" - common ground

Answer 2

it seems he needs 12 volts and I have 5 s adruins)
