Reliable Solid State Switching: G3MB-202P SSR architecture enables stable AC load control without mechanical contact wear or switching noise.
Wide Controller Compatibility: Low-level trigger input supports direct integration with Arduino, Raspberry Pi, PLC systems, and embedded microcontroller platforms.
Efficient Multi-Channel Control: Four independent relay channels allow simultaneous switching of lighting, heaters, motors, and industrial electronic equipment.
Enhanced Electrical Isolation: Integrated phototriac isolation structure helps improve operational stability and reduce interference in automation systems.
Simplified Industrial Integration: Pre-assembled module design with onboard LED indicators supports fast installation, diagnostics, and maintenance workflows.
The Elecbee 4 Channel 24V Solid State Relay Module is an industrial SSR control board designed for reliable switching of AC loads in automation systems, embedded control applications, smart IoT devices, industrial equipment, and microcontroller-based projects.
Built with G3MB-202P solid state relays, the module supports control of up to four independent AC loads with switching capability up to 240V AC at 2A per channel. The low-level trigger design enables direct interfacing with microcontrollers, PLC systems, Arduino platforms, Raspberry Pi boards, and other embedded controllers.
Unlike traditional mechanical relays, the solid-state relay architecture operates without mechanical contacts, helping reduce switching noise, contact wear, and maintenance requirements. The integrated phototriac isolation structure improves electrical isolation and switching stability in industrial electronic environments.
The module operates from a 24V DC power supply with approximately 160mA current consumption and includes LED status indicators for each relay channel, simplifying troubleshooting, monitoring, and system diagnostics during operation.
Designed for automation and power control applications, the SSR board is suitable for lighting control systems, industrial heaters, motors, pumps, fans, thermostats, incubators, smart appliances, and industrial machinery control systems.
The pre-assembled module design supports rapid integration into embedded electronics projects, industrial control panels, robotics systems, and IoT automation equipment.
