Supporting up to 10A load at 250V AC or 30V DC, it features selectable high/low trigger modes, clear LED indicators, and a fault-tolerant design that ensures continuous operation even under wiring faults. Ideal for professional-grade automation and IoT projects requiring reliable, flexible relay control. ## Description Feature: Module Size: 73x50x18.5mm (LxWxH) 4 Fixed Holes for Screw: Diameter 3.1mm Work Voltage: 5V Quiescent Current: 5mA Max Current: 190mA Trigger Current: 3-5mA Low Level Trigger Current: 0-1.5V High Level Trigger Current: 3-5V Input Interface: 1. DC+: 5V positive power supply 2. DC-: 5V negative power supply 3. IN: corresponding with trigger signal level of relay Output Interface: 1. NO: normally open interface 2. COM: common interface 3. NC: normally close interface Trigger Mode Configuration: The module has a trigger level selection terminal, each relay trigger level can be individually controlled, through the short-circuit cap to control. COM side is common, in the middle; When the LOW (L) terminal is connected to the common terminal, it is a low level trigger; when the HIGH (H) terminal is connected to the common terminal, it is a high level trigger. Normally Open Interface Work Mode: COM port connect with loaded AC live line or DC positive power supply, NO port connects with loaded AC zero line or DC negative power supply, the load circuit is disconnected, when there is trigger signal iniput, relay pick up, and circuit connected, load work. Normally Close Interface Work Mode: COM port connect with loaded AC live line or DC positive power supply, NC port connects with loaded AC zero line or DC negative power supply, the load circuit is close, and load work normally. When there is trigger signal iniput, relay disconnect, and load is off work. Package Include: 1pcs 5V 4 Channel High/Low Trigger Relay Module ## Features - Work Voltage: DC 5V, Max Load for Output: AC 250V/10A, DC 30V /10A. - Trigger Current 5A, can be used to all kinds of Single Chip Microcomputer IO control triggering, normally open and normally close two work mode. - By switching the trigger level selection terminal to set 3-5V high level or 0-1.5V low level trigger controlled. - Adopting patch piece opto-isolator, green power light, red relay status light, strong drive capability, stable performance, clear work condition. - Fault tolerant designed, humanized lead wire terminals, even the control line break off, the relay still keep working. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07BDJJTLZ | | Best Sellers Rank | #417,813 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1,556 in Electrical Relays | | Brand Name | DZS Elec | | Coil Voltage | 5 volts | | Connector Type | Screw | | Contact Current Rating | 10 A | | Contact Material | Silver | | Contact Type | Normally Closed | | Current Rating | 10 A | | Customer Reviews | 4.2 4.2 out of 5 stars (44) | | Maximum Switching Voltage | 250 volts | | Minimum Switching Voltage | 1.5 volts_of_direct_current | | Model | RELAY-R5V-4C | | Mounting Type | PCB Mount | | Operation Mode | Off | | Part Number | RELAY-R5V-4C | | UPC | 786738638004 | | Unit Count | 1 Count | ## Product Details - **Connector Type:** Screw - **Contact Material:** Silver - **Contact Type:** Normally Closed - **Current Rating:** 10 A - **Mounting Type:** PCB Mount ## Images ![5V 4 Channel Relay Optocoupler Isolation Module Red Board 3-5V High and 0-1.5V Low Level Triggered Load AC 0-250V / DC 0-30V 10A SCM IO Control - Image 1](https://m.media-amazon.com/images/I/71x5CobURnL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - DZS Elec 5V 4 Channel Relay Optocoupler Isolation Module Red Board 3-5V High and 0-1.5V Low Level Triggered Load AC 0-250V / DC 0-30V 10A SCM IO Control - lkelyonewy 5.5 x 2.1 mm DC Power Jack Socket Threaded Female Panel Mount Connector Adapter with Dustproof Plug 6Pack - 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 --- ## 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.co/products/123870423-5v-4-channel-relay-optocoupler-isolation-module-red-board-3](https://www.desertcart.co/products/123870423-5v-4-channel-relay-optocoupler-isolation-module-red-board-3) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-08-25*
