Good price! Got a backup... It's in an outdoor enclosure so I don't care about the noise (yes, it's a mechanical relay) or the LED (nice visual feedback). Easy to integrate with an Arduino and I think it'll do just fine. The system doesn’t stay out in the winter but it's there during the 100°+ heat. I have not experienced any negative issues with the Arduino and I assume it's optically isolated to the controller/signal. Review: Easy use aslong as you get the right voltage ratings - Works as expected, I previously got the 12.0 volt version by mistake but was still able to get it to work with an extra power supply and connecting the grounds, but with the 5.0 volt version I was able to I was able to remove the added power supply and just swap in the same connections. ## Features - It is 4 Channel Isolated 5V 10A Relay Module, each relay can individually switch on/off by an opto-isolated digital input, Standard interface can be directly connected with microcontrollers and be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, DSP, etc., very convenient. - Equipped with high-current relay, maximum load: AC250V 10A, 15A 125VAC, DC30V 10A; Trigger current of opto-isolator: 5mA. - RELIABLE: Fault-tolerant design, even if the control line breaks, the relay will not move; With optical coupling isolation, triggering more reliable, more stable. - EASY to INSTALL: Equipped with screwed terminal plate and fixed bolt holes(diameter: 3.1 mm) on both sides for easy installation. - High/Low level trigger can be selected by jumper. Very versatile, you can reverse the input logic with the jumper. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08PP8HXVD | | Best Sellers Rank | #81 in Single Board Computers (Computers & Accessories) | | Brand Name | ANMBEST | | Coil Voltage | 5 Volts | | Contact Current Rating | 10 Amps | | Contact Type | Normally Open | | Current Rating | 10 Amps | | Customer Reviews | 4.5 4.5 out of 5 stars (119) | | Manufacturer | ANMBEST | | Minimum Switching Voltage | 5 Volts (DC) | | Model | ANMBEST_MD314-319 | | Operation Mode | Off | | Part Number | ANMBEST_MD314-319 | ## Product Details - **Brand:** ANMBEST - **Coil Voltage:** 5 Volts - **Contact Type:** Normally Open - **Current Rating:** 10 Amps - **Operation Mode:** Off ## Images ![2PCS 4 Channel 5V Relay Module with Optocoupler High or Low Level Trigger Expansion Board for Raspberry Pi Arduino - Image 1](https://m.media-amazon.com/images/I/81f9a7lXZjL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Compact board that flips the relays reliably and cheaply! *by A***R on July 12, 2025* Reliably switching 24v sprinkler solenoid valves for over a year.
