(-43%)2-Channel 5 V Relay Module with optocoupler isolation. Allows control of two independent high-power loads (up to 10 A) via 5 V logic (e.g. Arduino / microcontroller), with LED indicators and screw-terminal outputs.
Product details
This 2-channel relay module is designed for interfacing microcontrollers (Arduino, ESP32/8266, MCU boards etc.) with higher-voltage or higher-current loads safely. It uses a 5 V DC supply and features optocoupler isolation on the input side to protect the logic/control circuitry from noise, spikes or interference from the relay coils and switched loads.
Each channel has its own relay (SRD-05VDC-SL-C or equivalent), capable of switching up to 10 A at 250 VAC (or up to ~30 V DC). The module supports either low-level or high-level triggering (depending on jumper / version), and includes indicator LEDs for power & relay status. Outputs are through screw terminals (COM / NO / NC) making it easy to wire external loads. Mounting holes are provided on the PCB for stable installation.
Ideal for home automation, robotics, IoT / embedded control projects, where you need to control two separate circuits from one microcontroller pin-set, while maintaining electrical isolation and reliability.
