Each relay channel supports configurable high or low level triggers, with clear LED indicators and screw terminal connections for professional-grade Arduino and automation projects. ## Description Description : 1. The module uses genuine quality relay, normally open interfaces Maximum load : AC 250V/10A, DC 30V/10A; 2. Using SMD OPTOCOUPLER isolation , driving ability , stable performance ; trigger current 5mA; 3 . The module voltage is 12V; 4 . Each way module can be set high or low triggered by jumper ;5 . Fault-tolerant design , even if the control line is broken , the relay will not operate ; 6 . The power indicator ( green ) , 8 relay status indicator ( red ) 7 . Interface design humane, all interfaces can be connected directly via terminal wiring leads , very convenient 8 . Module size : 141.5mm * 50mm * 18.5mm ( L * W * H ) 9 . Has four mounting bolts holes , hole 3.1mm, pitch 136mm * 44.5mm Module Interface :1. DC +: 12V positive power supply 2. DC-: negative power connection 3. IN1-IN8: each way based on the settings , can be high or low to control the corresponding relay Relay outputs :24 line interface, the interface can be directly connected to all leads , user-friendly 1. NO1 - NO8: normally open relay interfaces , relay before the vacant after the pull shorted with COM 2. COM1 - COM8: Relay Common Interface 3. NC1 - NC8: normally closed relay interface relay shorted with COM ago , after the pull- vacant High and low trigger selection : 1.S1-S8 in order to relay a road -8 way high and low trigger selection ;2.Com with low short circuit , triggering the corresponding relay is low , while the high end of the short com high trigger Package Included:1*12V 8 Channel Relay Module With Optocoupler ## Features - 12V 8 Channel Relay Module With OPTO-Isolated High And Low Level Trigger - The module Operating voltage 12V; - The module can be high or low by a jumper setting trigger; - Fault-tolerant design, even if the control line is broken, the relay will not operate; - The power indicator (green), the relay status indicator (red). ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00LW2GA5Y | | Brand Name | HiLetgo | | 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 | | Item Weight | 50 g | | Manufacturer | HiLetgo | | Maximum Switching Current | 10 Amps | | Maximum Switching Voltage | 250 Volts | | Model | 3-01-0348 | | Mounting Type | Screw Mount | | Operation Mode | Automatic | | Part Number | 3-01-0348 | | UPC | 702082656006 | | Unit Count | 8.0 Count | | Wattage | 60 Milliwatts | ## Product Details - **Connector type:** Screw - **Contact material:** Silver - **Contact type:** Normally Closed, Normally Open - **Current rating:** 10 Amps - **Mounting type:** Screw Mount ## Images ![12V 8 Channel Relay Module with OPTO-Isolated High and Low Level Trigger 8 Ways Relay Switch Module for Arduino - Image 1](https://m.media-amazon.com/images/I/71iHfA+0UhL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - HiLetgo 12V 8 Channel Relay Module with OPTO-Isolated High and Low Level Trigger 8 Ways Relay Switch Module for Arduino - HiLetgo 12V 4 Channel Relay Module with OPTO-Isolated Support High and Low Level Trigger - HiLetgo 2pcs DC 12V 2 Channel Relay Module with Isolated Optocoupler High and Low Level H/L Level Trigger Module Triggered by DC 12V --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/256334325-12v-8-channel-relay-module-with-opto-isolated-high-low](https://www.desertcart.com.cy/products/256334325-12v-8-channel-relay-module-with-opto-isolated-high-low) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-07-16*
