2-Channel Solid State Relay (SSR) Module – 12V DC Input, 240V AC Output, Low-Level Trigger

This 2-Channel Solid State Relay (SSR) Module is designed for controlling high-voltage AC loads with a low-level trigger signal. It utilizes Omron G3MB-202P solid-state relays, which provide reliable and noise-free switching of AC loads. Unlike mechanical relays, this SSR module has no moving parts, offering higher durability, faster switching speeds, and silent operation.

The module operates on a 12V DC input and can switch up to 240V AC loads at 2A per channel, making it ideal for applications such as home automation, industrial control, motor control, and lighting systems. Each relay is optically isolated, ensuring safe and interference-free operation when interfacing with microcontrollers like Arduino, Raspberry Pi, ESP8266, ESP32, and PLCs.

This SSR module is low-level triggered, meaning that a LOW (0V) signal activates the relay, making it easy to integrate with 3.3V or 5V logic controllers.

Key Features:

• 2-Channel Solid State Relay (SSR) – Allows independent control of two AC loads.
• Low-Level Trigger Input – Activates when the input signal is LOW (0V).
• 12V DC Control Voltage – Compatible with various microcontrollers and control circuits.
• 240V AC Load Switching – Supports up to 2A per channel at 50/60Hz.
• Omron G3MB-202P SSRs – High-quality, reliable, and durable solid-state relays.
• Optocoupler Isolation – Ensures safe and interference-free operation.
