The MolSmart MS-B004 Relay Board 4-Channel is a professional-grade Ethernet and WiFi relay module engineered for modern home and building automation projects. Designed for DIN rail installation, it delivers 4 independent relay outputs — each rated at 10A — and 4 corresponding digital inputs, enabling full bidirectional control and real-time status feedback from a single compact module.

Native integration via TCP/IP makes it compatible with the industry's leading automation platforms, including Control4, Savant, Crestron, RTI, Nice, Hubitat, and Home Assistant. Platform-specific drivers are included at no additional cost, and the Control4 driver is officially certified, ensuring verified performance and seamless compatibility within Control4 ecosystems.

Configuration is handled through a built-in web interface accessible via standard browser, with a dedicated onboard Access Point (AP) for direct setup without a network. Advanced features include a native scheduler for time-based automation, scene creation directly on the module, and a hardware watchdog for maximum uptime. Communication protocols include API TCP/HTTP and MQTT, enabling flexible integration with custom systems.

Power is supplied via two redundant 12VDC inputs, each independently monitored — ensuring the module stays online even if one supply fails. This redundancy is particularly valuable in mission-critical residential and commercial installations. Manufactured in Brazil and FCC and UL certified for the US market.

For end users who prefer standalone operation without a central automation controller, the MolSmart iOS and Android app provides full control directly from a smartphone. The module is also compatible with Amazon Alexa for voice control integration.
