5V 2 CH SSR Low Level Solid State Relay Module AC 240V/2A

The 5V 2-Channel Solid State Relay Module (SSR) is designed for reliable, silent, and fast AC load switching. Using high-quality G3MB-202P relays, this module ensures long-lasting operation, noise-free performance, and precise control of electrical appliances and industrial devices. Ideal for Arduino, Raspberry Pi, home automation, industrial control systems, and DIY electronics, this SSR module provides safe and efficient switching of AC loads up to 240V/2A per channel.

Key Features:

• Rated Output Load: 100V ~ 240V AC (50Hz/60Hz), 2A per channel
• Rated Input Power: 5V DC, 160mA (all channels ON)
• Low-Level Trigger: Compatible with standard digital control signals
• Status Indicators: LED indicators for each channel for easy monitoring
• Control Signal:
  • Low Signal (0V – 2V / GND) → Relay ON
  • High Signal (3.3V – 5V / floating) → Relay OFF
• Durable and Reliable: Long lifespan, stable performance, and silent switching
• Compact Design: Easy to integrate into any electronic project or control system

Connections:

• DC+ : Connect to positive power supply (5V DC)
• DC- : Connect to negative power supply (GND)
• CH1 : Signal trigger for relay channel 1 (low-level trigger)
• CH2 : Signal trigger for relay channel 2 (low-level trigger)

Triggering Modes:

High-Level Triggering: Apply a positive voltage relative to ground to the trigger terminal to activate the relay.
Low-Level Triggering: Connect the trigger terminal to ground (0V) to switch the relay ON.
This dual triggering support ensures compatibility with various microcontrollers and control systems.

Applications:

• Home automation systems (lights, fans, ACs)
