Description of πŸ“‘ Optocoupler Support Trigger by HiLetgo Channel

The module uses genuine quality relay, normally open interfaces , Maximum load: AC 250V/10A, DC 30V/10A. Using SMD optocoupler isolation, strong driving capability, stable performance; trigger current 5mA. Fault-tolerant design, even if the control line is broken, the relay will not move. The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient. The Module can be set by jumper high or low trigger.

Used to control the performance of my 3D printer with the M80 and M81 gcode commands.

I actually bought this relay not expecting to use the LOW trigger option. Actually I just wanted a simple 5V relay that I wanted to control via mosfet. It turns out that the output of the trigger contacts gives out only 2.5 volts, which is not enough to work with. I connected this relay to a 5V supply as directed, connected one of my 120V wires to my 24V supply, set the jumper low and connected it to a pin that supplies 2.5V, and it works great, allowing me to turn my 3d printer on and off…

Pros
  • Human nature interface design, all interfaces are available through the direct connection of the terminal, very convenient.
Cons
  • weak

That does not work. via industrial electronics

UPDATE: These are identical to Jungner's and after testing 6 at low voltage only 7 worked. And I don't have high hopes for durability. just trash. I'll be back. I built my project and tested the low voltage load and everything worked for my test case. As soon as I connect the correct AC load across the relay it becomes unreliable. If I disconnect the AC load and try the low voltage test again, it still doesn't work. It opens normally, but then does not return to the closed state without lightly

Pros
  • using SMD optocoupler isolation, strong control ability, stable performance; actuation current 5mA.
Cons
  • Doubtful

Firmly. Works as it should.

I use this in a small tracked robot chassis as a primitive estop for motors when my power supply sensor detects an overcurrent condition. I'm very conscientious about this project so I took some measurements. It works well with both 3.3V and 5V power supplies. There are DC+ and DC inputs for power and a trigger input for relay activation. The relay has contacts for both normally open and normally closed operation. Active high or active low triggers are selectable with a single jumper. It works…

Pros
  • The module uses real quality relays, normally open interfaces. Max load: 250VAC/10A, 30VDC/10A.
Cons
  • Drill Pack
