The MolSmart MS-B016 Relay Board 16-Channel delivers exceptional I/O density for large residential and light commercial automation projects. With 16 relay outputs — each rated at 10A NO/NC — and 16 corresponding digital inputs on a single DIN rail module, the MS-B016 is designed to efficiently handle extensive lighting, HVAC, gate, and access control applications within a minimal panel footprint.

Full TCP/IP integration is supported natively for Control4, Savant, Crestron, RTI, Nice, Hubitat, and Home Assistant, with all drivers provided at no cost. The Control4 driver is officially certified, making the MS-B016 a proven choice for Control4 dealers requiring a high-density relay solution with a certified integration path.

The module's built-in web interface and dedicated onboard Access Point allow full configuration and programming without additional software or network dependency. Integrators can define time-based automations using the native scheduler, create complex scenes directly on the device, and rely on the built-in hardware watchdog for continuous self-monitoring and fault recovery. API TCP/HTTP and MQTT protocols ensure compatibility with virtually any custom integration.

Power redundancy is a core design feature: two independent 12VDC power inputs, both monitored in real time, guarantee continuous operation even if one supply is lost. Ideal for projects where reliability is non-negotiable. FCC and UL certified. Manufactured in Brazil.

The MolSmart app (iOS and Android) enables full standalone control when no automation controller is present. Amazon Alexa voice control is also natively supported.
