Description of ๐Ÿ”Œ Arduino-Compatible Optocoupler Isolation Channel Trigger

Input voltage is 5V, the max load of interface is AC 250V/10A, DC 30V/10A. SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA. Can be set high or low level trigger with jumper. With Fault Tolerant Design, humanized terminals, even if the control line is broken, the relay will not take any action. With green power light, red relay status indicator light, can directly reflect the current module working condition.

Essential for Reliable Control Signal

This optocoupler isolation trigger is a must-have for anyone in the Industrial and Scientific field. It provides reliable signal isolation to prevent interference and improve performance. The compact size and easy installation make it a great addition to any project. However, the cost may be a bit high for some budgets. Overall, this product is top-notch and delivers excellent results.

Pros
  • Provides reliable optical isolation between an input signal and an output signal.
Cons
  • Requires additional wiring and setup compared to non-isolated triggers.

Worked like clockwork

Worked well and now I have a new Raspberry Pi controlled smart sprinkler system that is 90% cheaper than anything else on the market. The controller works very well and would buy it again.

Pros
  • Industrial Electrics
Cons
  • Expensive

Arduino Mega doesn't always drive it active low or active high

I needed a 12 volt driver, not a 5 volt driver, this seemed like a good replacement (red in photo) 5 volt board (blue in the photo), but the same Arduino sketch does not enable this board. All 4 relays are activated when Arduino is connected. To be clear, nothing happens without an input, and choosing Active High or Active Low works on the bench. However, once the Arduino is connected regardless of the input selector jumper. Relays switch on.

Pros
  • Controls and Indicators
Cons
  • Piggy Bank Price
