Designed for low-level 5V DC triggers, it’s ideal for professional and DIY electronics requiring efficient, space-saving power control. ## Description Product description: This relay is an electrically operated device. It uses a low level triggered control signal (3.3 V - 5 V DC) to control the relay. Triggering the relay operates the normally open or normally closed contacts. It is frequently used in an automatic control circuit. To put it simply, it is an automatic switch to control a high current circuit with a low current signal. The advantages of using a relay are seen in its lower inertia of the moving parts, stability, long-term reliability and small volume (size). It is widely used in devices for power protection, automation technology, sport, remote control, reconnaissance and communication, as well as in devices of electro-mechanics and power electronics. It also contains an actuator module (output) which can energize or de-energize the connection of controlled circuit. There is an intermediary part between input part and output part that is used to couple and isolate input current, as well as actuate the output. When the rated value of input (voltage, current, temperature, etc.) is above the critical value, the controlled output circuit of relay will be energized or de-energized.The features of the 2-channel relay module are as follows:Good for safe control of higher amperage circuits. In power systems, the lower current can control the higher one.2-channel high voltage system output, meeting the needs of single channel control.Wide range of controllable voltages.Being able to control high load current, which can reach 240 V, 10 A or 125 V, 15 A.With a normally-open (NO) contact and a normally-closed (NC) contact.Package includes: 1 x 2-channel, 5 V relay module. ## Features - Relay module, model: JQC-3FF-S-Z, 2-channel. - Voltage to operate: 5 V DC. - Size: 50 mm x 37 mm x 18 mm (L x W x H), colour: Blue relays on a black PCB. - Weight: 35 g. - Load: 10 A, AC 250 V, 15 A, 125 V contacts rated for AC interruption. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Wonderwing | | Part number | 2CH-JQC-3FF-S-Z | | Item Weight | 20 g | | Package Dimensions | 10.4 x 7 x 1.4 cm; 20 g | | Manufacturer reference | 2CH-JQC-3FF-S-Z | | Plug profile | PCB Mount | | Batteries included? | No | | Batteries Required? | No | ## Product Details - **Contact type:** normally closed,normally open - **Current rating:** 15 Amps - **Mounting type:** PCB Mount - **Brand:** Tongling - **Operation mode:** Automatic ## Images ![5 V DC 2-channel, low level trigger, power relay module, JQC-3FF-S-Z, 10 A, 250 V AC, 15 A, 125 V AC, RBTMKR - Image 1](https://m.media-amazon.com/images/I/91AtEu-UTwL.jpg) ![5 V DC 2-channel, low level trigger, power relay module, JQC-3FF-S-Z, 10 A, 250 V AC, 15 A, 125 V AC, RBTMKR - Image 2](https://m.media-amazon.com/images/I/91sy3WjWd-L.jpg) ![5 V DC 2-channel, low level trigger, power relay module, JQC-3FF-S-Z, 10 A, 250 V AC, 15 A, 125 V AC, RBTMKR - Image 3](https://m.media-amazon.com/images/I/91FotLAVfAL.jpg) ![5 V DC 2-channel, low level trigger, power relay module, JQC-3FF-S-Z, 10 A, 250 V AC, 15 A, 125 V AC, RBTMKR - Image 4](https://m.media-amazon.com/images/I/91EkhZGefZL.jpg) ![5 V DC 2-channel, low level trigger, power relay module, JQC-3FF-S-Z, 10 A, 250 V AC, 15 A, 125 V AC, RBTMKR - Image 5](https://m.media-amazon.com/images/I/914jlLJBWpL.jpg) --- ## 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.pl/products/61959393-5-v-dc-2-channel-low-level-trigger-power-relay](https://www.desertcart.pl/products/61959393-5-v-dc-2-channel-low-level-trigger-power-relay) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-26*
