Description of πŸ”Œ Weewooday Channel Optocoupler Isolation Expansion: Enhancing Signal Integrity and Protection

Relay module: this relay board supports high and low level trigger and can be controlled by any 5V digital output of the microcontroller. Parameter details: maximum load of normally open interface: AC 250v/ 10A, DC 30v/ 10A, trigger current is 5mA; The 5v relay control board adopts SMD optocoupler isolation, which has strong driving ability and stable performance. Practical design: with fault-tolerant design, the relay module will not operate even if the control line is disconnected; All interfaces can be provided through directly connected terminal s since the humanized interface design, it is very convenient to use. High compatibility: the relay module can be directly controlled by the 5V logic signal provided by the microcontroller, suitable for 8051, Raspberry Pi, PIC, DSP, ARM, AVR, MSP430, TTL logic, etc. Wide application: this 5V relay board can be applied with Raspberry/ CNC machine/ ARM/ PIC/ AVR/ MCU/ PS4 and more.

Impressive Isolation Expansion for Industrial Electrical

Based on my experience, this Optocoupler Isolation Expansion is a must-have for Industrial and Scientific applications. It works perfectly in controlling and isolating the inputs and outputs. The compact design makes it easy to install and operate. The high isolation voltage makes it safe to use. On the downside, the instructions could be clearer. Overall, a great investment for anyone in the electrical control field.

Pros
  • Provides reliable and safe isolation between high and low voltage circuits, reducing the risks of electrical interference and damage to components.
Cons
  • Optocouplers might require additional circuit design efforts and may increase the cost of the final product.

used them for 4 years

For many years some of them stopped working after about 3 years but I used them quite intensively and regularly. Only one of the 35 was dead on arrival, with more than half still operational.

Pros
  • Certified
Cons
  • Cable is shorter than other picks

Next time I will look for a more compact device

They are fine, delivered as seen in the photos. With this or other devices, just pay attention to the size of the circuit board if that bothers you. I'm trying to use some of these for home automation and there are a few options that take up less space than this board. I would rather have the screw terminal and jumper on the low voltage side that are optional in the kit. So you can omit them if you'd rather solder the wires directly to the board instead. This would make the device much lower on

Pros
  • Delivery was very fast
Cons
  • Crumpled
