## Description

Module Description: The module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA The module voltage 5V The module can be set high or low triggered by jumper Fault-tolerant design, even if the control line is broken, the relay will not operate Power indicator (green), relay state indicator (red) Interface design user-friendly, all interfaces are available through the wiring terminal direct connection leads, very convenient Module size: 50mm * 26mm * 18.5mm (L * W * H) 4 mounting bolts holes, hole 3.1mm, 44.5mm * 20.5mm spacing Module interface DC +: positive power supply (voltage by relay requirements, 5V.9V.12V and 24V selection) DC-: negative one IN: can be high or low level control relay Relay outputs NO: normally open relay interfaces, relay before hanging, pull back and COM short-circuited COM: Relay Common Interface NC: normally closed relay interfaces, relay and COM short-circuited before, after the pull-vacan

Review: Can work with as low as 5V. - My use is to power up a USB power supply using a USB port on computer as trigger. I have some lighting that I want to always come on when the computer is powered on or comes out of standby. The PCI-E USB card I'm using powers down in standby so I'm running a cable from that to trigger this relay which will close the AC circuit on a USB power supply. I could've potentially powered them from the USB card on the computer but I'd rather subcontract this power demand to a lesser device. Using my inline USB voltage and current meter, (so-so quality, readings always seem appropriate and correlate with the load put on it but I haven't checked it against a VOM), standby current was too low to read and with relay engaged it showed 80mA. Resolution on this USB meter is only 2 decimal places so something under 10mA for unclamped state. I could've just used a 5V relay for this task but I haven't seen any with 1/4" spade terminals and it's convenient having a board to solder the 120V wires to. For the price I went ahead and got a 5 pack for future projects. I was able to use only USB power by connecting red(+ from USB cable) to DC+ and IN terminals, and black (- from USB cable) to DC- terminal. This initial use is just for "bling" but I can imagine many applications where having switch control conditional to a computer being on or off would be handy.
Review: Great value and simple to use with a little research - These are actually quite simple to use after a little digging. The datasheet is terrible but the manufacturer has placed these relays on a breakout board that allows you to use a HIGH or LOW signal to activate the relay. I'm using mine for a class project involving a temperature controller that turns on a fan or heating element depending on the temp. They are rated for up to 250V AC and use an infrared optocoupler to separate the digital control circuit (low voltage) from the analog output (higher voltage). Very happy with my purchase as many desertcart electronic components are very inconsistent in quality and reliability coming when they come from foreign manufacturers. Would recommend.

### ⭐⭐⭐⭐⭐ Can work with as low as 5V.

### ⭐⭐⭐⭐ Works with Raspberry Pi
*by A***G on August 21, 2020*

I'm using this with two Raspberry Pi boards (one a 3B+, the other a 2B) connecting both the 5V to power the solenoid board and using the PI 3.3V GPIO to turn on/off. One of the 4 units was defective out of the box but the others are working. For the money, they are a good choice. Note that there is a severe limit on the current available for GPIO switching from the Pi, so the single-channel model would be the only viable choice. I am able to use this to power a 3D printer on/off by switching the AC power using the OctoPrint PSU control add-in, which simply raises a configurable GPIO pin.
