Review: These work great for use with the arduino since you can grab the 5V on board the unit to power it up. Using the 3.3V for power will not pick these relays so you have to use the 5V but other then that they are great relays and can run up to 10 amps which is great for certain projects. Review: It works really well to trigger a high current device using a low level signal ## Features - 【Control Devices】The 2-channel relay module uses genuine high quality DC12V relay and SMD opto-isolator supporting high/low level trigger, widely apply to control various AC/DC appliances, and other devices with large current. - 【Load Range】NO(Normally open) maximum load < AC 250V/10A, < DC 30V/10A. Trigger current of opto-isolator: 5mA. - 【Fault-tolerant Design】The relay will not operate even if the control line is disconnected. - 【Universal Interface】Equipped with screwed terminal plate and fixed bolt holes(diameter: 3.1 mm) on both sides for easy installation. - 【High Compatibility】The relay module can be controlled directly by 12V logic signals from microcontroller(8051, AVR, PIC, DSP, ARM, Pi, MSP430, TTL logic etc). ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B085N49S79 | | Brand Name | Valefod | | Coil Voltage | 12 Volts | | Connector Type | Screw | | Contact Current Rating | 10 Amps | | Contact Material | Silver | | Contact Type | Normally Closed, Normally Open | | Current Rating | 10 Amps | | Customer Reviews | 4.3 4.3 out of 5 stars (103) | | Manufacturer | Valefod | | Maximum Switching Current | 10 Amps | | Maximum Switching Voltage | 12 Volts | | Minimum Switching Voltage | 12 Volts | | Mounting Type | Panel Mount | | Operation Mode | Automatic | | Part Number | VA-0186-8 | | Specification Met | Vcc | | UPC | 722453988314 | ## Product Details - **Connector type:** Screw - **Contact material:** Silver - **Contact type:** Normally Closed, Normally Open - **Current rating:** 10 Amps - **Mounting type:** Panel Mount ## Images ![[2-Pack] DC 12V Relay Module 2-Channel Relay Switch with Optocoupler Isolation High/Low Level Trigger - Image 1](https://m.media-amazon.com/images/I/71J7MeakRAL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***A on 15 August 2022* These work great for use with the arduino since you can grab the 5V on board the unit to power it up.
