4 Channel Solid State Relay Module 5V Low Level Trigger for Arduino

The 4 Channel Solid State Relay (SSR) Module is a compact, no-mechanical-contact relay board featuring four independent solid state relay channels. It supports low level trigger (active LOW) control, making it directly compatible with Arduino, Raspberry Pi, and other 5V microcontrollers. Each channel has screw terminal connectors for both control and load sides.

• Channels: 4 independent SSR channels
• Control Voltage: 5V DC (TTL compatible)
• Trigger Type: Low Level (Active LOW)
• Load Voltage: DC 5V – 60V
• Load Current: Up to 2A per channel
• Connectors: Blue screw terminals for input (DC+, DC-, CH1–CH4) and output
• Onboard power indicator LED
• No mechanical wear — silent, fast switching
• Mounting holes for easy installation
• Compatible with Arduino, Raspberry Pi, ESP32, STM32

Ideal for DC motor control, LED dimming, solenoid valve control, home automation, and any application requiring silent solid-state switching.
