Featuring optical isolation for stable triggering and a heat-dissipating groove design, it integrates seamlessly with various microcontrollers via screw terminals, making it ideal for professional-grade automation, motor control, and safety applications. ## Description Product Description The Relay is an electrical switch responds to a signal from the microcontroller to control AC circuits Open and OFF. High and Reliable compatibility with various microcontrollers, which facilitates integration into numerous projects. Rire retardant Material to avoid buring from the electrical accident. Groove design may help increase the heat dissipation area of the relay, thereby improving its heat dissipation performance The main functions of relays include automatic regulation, safety protection, switching circuits, etc. It is actually a kind of ‘automatic switch’ to control the operation of large currents with small currents. In the field of motor control, relays are often used to control the starting, stopping and reversing of motors. Review: Great buy. - Just what I needed. I needed a very quick repair for a project I was working on, and these arrived the next morning. They were perfect for repairing a faulty relay and worked a treat. Fast delivery and did exactly what I needed them to do. Review: Useless, probably got unlucky - Didn't work, led came on but relay didn't switch. NC or NO just stayed the same. Not worth returning due to price. Ended up getting a 240v din rail mounted contactor instead. Cheap electronics are a bit of a risk as always, just got unlucky I guess. ## Features - Package Include: 1 Pcs 1 Channel Relay Module. - Maximum Load : AC 250V/10A, DC 30V/10A. - Voltage: 12V Trigger Current: 5mA - Relay Module Designed With Fault-Tolerant , Even If The Control Line Breaks, The Relay Will Not Move; With Optical Coupling Isolation,Triggering More Reliable and Stable - Equipped With Screwed Terminal Plate and Fixed Bolt Holes, the Relay can Connect With Microcontrollers and be Controlled by a Wide Range of Microcontrollers ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D9NKVFH9 | | Best Sellers Rank | 4,215 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 2 in Electromechanical Relays | | Brand | Innfeeltech | | Coil Voltage | 12 Volts (DC) | | Connector Type | Quick coupling or screw | | Connector type | Quick coupling or screw | | Contact Current Rating | 10 Amps | | Contact Material | Silver | | Contact Type | Normally Open | | Contact material | Silver | | Contact type | Normally Open | | Country Of Origin | China | | Current Rating | 10 Milliamps | | Current rating | 10 Milliamps | | Customer Reviews | 4.2 out of 5 stars 43 Reviews | | Manufacturer | Innfeeltech | | Manufacturer Part Number | DC13-201Y | | Maximum Switching Voltage | 12 Volts | | Minimum Switching Voltage | 12 Volts (DC) | | Model Number | DC13-201Y | | Mounting Type | Screw Mount | | Mounting type | Screw Mount | | Operation Mode | Automatic | ## Product Details - **Connector type:** Quick coupling or screw - **Contact material:** Silver - **Contact type:** Normally Open - **Current rating:** 10 Milliamps - **Mounting type:** Screw Mount ## Images ![1pcs DC 12V Relay Module 1 Channel Relay with Optocoupler High or Low Level Trigger Expansion Board - Image 1](https://m.media-amazon.com/images/I/519vcnECQtL.jpg) ![1pcs DC 12V Relay Module 1 Channel Relay with Optocoupler High or Low Level Trigger Expansion Board - Image 2](https://m.media-amazon.com/images/I/61PUHLrk46L.jpg) ![1pcs DC 12V Relay Module 1 Channel Relay with Optocoupler High or Low Level Trigger Expansion Board - Image 3](https://m.media-amazon.com/images/I/71q9A5MLBAL.jpg) ![1pcs DC 12V Relay Module 1 Channel Relay with Optocoupler High or Low Level Trigger Expansion Board - Image 4](https://m.media-amazon.com/images/I/71KhZUk50lL.jpg) ![1pcs DC 12V Relay Module 1 Channel Relay with Optocoupler High or Low Level Trigger Expansion Board - Image 5](https://m.media-amazon.com/images/I/61iRb7oyzyL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great buy. *by B***R on 23 December 2025* Just what I needed.
