It supports 5V-12V TTL signals to control DC or AC loads up to 220V, featuring both normally open and normally closed contacts with tungsten material for durability. Ideal for Arduino, ARM, PIC, and AVR MCU applications, it enables seamless control of motors, LED strips, and other power-demanding appliances. ## Description The 5V relay module is suitable for SCM development, home appliance control. It is with 5V~12V TIL control signal which can control DC / AC signal. The module is perfect for common development application. Color: Blue + black Suitable for SCM development, home appliance control 5V-12V TTL control signal, can control DC/AC signal Can control 220V AC load Useful to control a motor, a led strip, or any other module How to use it: Just connect a digital output of your board to your relay module, and you can control a power-demanding appliance with the digital signal ## Features - Microcontroller development board can be used as modules, can be used as appliance control - 5V - 12 V control signal of the TTL - Control DC or AC signals can control the 220V AC Load - There is a normally open and open normally closed contact - Useful to control a motor, a led strip, or any other module. How to use it: Just connect a digital output of your board to your relay module, and you can control a power-demanding appliance with the digital signal ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00VRUAHLE | | Best Sellers Rank | #41,310 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #4 in Sensor Blocks | | Brand | TOLAKO | | Brand Name | TOLAKO | | Coil Voltage | 12 Volts | | Connector Type | Through Hole | | Contact Material | Tungsten | | Contact Type | Normally Closed, Normally Open | | Customer Reviews | 4.6 out of 5 stars 383 Reviews | | Manufacturer | Tolako | | Maximum Switching Voltage | 220 Volts | | Minimum Switching Voltage | 5 Volts | | Model | BJ-DT0Y-001 | | Mounting Type | PCB Mount | | Number of Terminals | 3 | | Operation Mode | Motor | | Part Number | 6458512 | ## Product Details - **Connector Type:** Through Hole - **Contact Material:** Tungsten - **Contact Type:** Normally Open, Normally Closed - **Mounting Type:** PCB Mount - **Brand:** TOLAKO ## Images ![5v Relay Module 5V Indicator Light LED 1 Channel Relay Module for Arduino ARM PIC AVR MCU - Image 1](https://m.media-amazon.com/images/I/51skTYXNy5L.jpg) ## Questions & Answers **Q: max wattage on 120v ac USA ?** A: There is a tough to find data sheet that does spec this unit at a max of 30vdc. Refer to this link for more info, http://electronics.stackexchange.com/questions/97721/why-ac-points-on-pcb-are-separated-by-a-holeThere are products that are very similar and rated for 120v ac use. **Q: Does it have optocoupler isolation?** A: No opto-coupled isolation. There is a small transistor onboard that is driving the relay and as someone else pointed out, the coil has a diode across it to supress the counter EMF of the coil. This relay requires very little to drive it as long as it's wired correctly ("+" to 5-12VDC, "-" to Ground, "s" to your digital output. The output is active high (when your output is high, the relay energizes). The screw terminals (NO = Normally Open, NC = Normally Closed, C = Common). **Q: How reliable are these? I bought one but it just died on me, the led lit but it wouldn’t switch anymore so I had to throw it away.** A: I've had two of these in service for over 2 years now with no issues. They are each separately controlling garage door momentary switches. They are each in a circuit with an Arduino activated by bluetooth to start the garage door motor from the momentary switch. They've worked great for me. **Q: Does this only work with official Arduinos?** A: No, it will work with anything that sends out a 5v digital signal (though I also had success with a 3v esp8266, so input tolerances are probably fairly wide ) ## Frequently Bought Together - Tolako 5v Relay Module 5V Indicator Light LED 1 Channel Relay Module for Arduino ARM PIC AVR MCU - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - Arduino Uno REV3 [A000066] – ATmega328P Microcontroller, 16MHz, 14 Digital I/O Pins, 6 Analog Inputs, 32KB Flash, USB Connectivity, Compatible with Arduino IDE for DIY Projects and Prototyping --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/15850652-5v-relay-module-5v-indicator-light-led-1-channel-relay](https://www.desertcart.at/products/15850652-5v-relay-module-5v-indicator-light-led-1-channel-relay) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-23*
