Description of πŸ”΄ Vogurtime 4 Ch 5V Relay Module w/ Optocoupler Isolation | High/Low Level Trigger | Red Relay Board

High Quality Module - the relay module uses genuine high-quality relays. The maximum load of the frequently opened interface is: AC 250v/10a, DC 30v/10a. Adopts SMD Optocoupler Isolation - Use two sets of fully isolated power supply system power, to ensure that the relay in the switch will have an impact on the signal circuit and can be freely switched to high level drive mode or low level drive mode. Trigger Current is 5mA. "High", "Low" Level Controllable - With a jumper cap, you can choose a low level control or a high level control, allowing the relay module to adapt to more occasions. It Has a Fault-Tolerant Design - Even if the control line is broken, the relay won't actuation. User-friendly Interface Design - All interfaces can be directly connected through the terminal block, which is very convenient

Partly defective for industrial electrical engineering

This board is very unreliable, not all relays can be activated at the same time and an order is required for it to work at all. Use the same power supply as the 8 channel relay and it will work.

Pros
  • Stable test results
Cons
  • There are disadvantages

Serious quality control problems.

Only 7 relays work on this one. The first thing I ordered none of the relays responded and one of the jumpers was broken. The first 4 relay modules were missing 2 jumpers. I think they are cheap for some reason.

Pros
  • Absolutely amazing!
Cons
  • Hard to say

3.3V and 5V logic compatible

It's useful to have this 4 channel relay board as it works equally well with 3.3V and 5V logic (although the power supply itself has to be 5V). Also, you can configure each channel individually to trigger the relay either high or low. With the jumper in the L (low) position, the input line rises to around 4.3V, allowing for an open collector driver, while at 5V only 2mA is required to activate the relay. In the jumper position H (high) the relay pulls in at 1.7V and drops out again when the…

Pros
  • Features a fail-safe design - even if the control line is broken, the relay will not operate.
Cons
  • Almost everything included

Great relay suitable for controls and indicators

If you are looking for a relay I can confirm this relay works great with a user configurable top or bottom trigger. I first ordered the ones I mistakenly ordered with only the low trigger. It stays on and only turns off when the relay trips. I suspect that since it's enabled 99% of the time it wears out quicker than this one, which can be set to start with high or low input. I just ordered more of these and just threw the low blue ones in the trash.

Pros
  • A dream come true
Cons
  • Can I add something

Compact but Versatile

Good compact but full featured relay module. When tested it draws 3mA at idle with an additional 55mA from the power supply for each relay switched on. The current to turn on the relay is also only 3mA, making it ideal for an Arduino or Raspberry Pi circuit. The connection is made via terminal strips at the input and output. add to the versatility. Each relay is rated for up to 10A at 30V DC or 10A at 220V AC. In long tests, nothing was too warm. The input circuit is switched individually so…

Pros
  • Regular Price
Cons
  • Expensive
