Review on 🔴 Vogurtime 4 Ch 5V Relay Module w/ Optocoupler Isolation | High/Low Level Trigger | Red Relay Board by Tiffany Thompson

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 either a 3.3-5V signal or a ground signal can activate the relay. And with dimensions of 72mm by 48mm, it doesn't take up much space. Overall this is excellent value for money.
