The MolSmart MS-B032 Relay Board 32-Channel stands as the highest-density single-unit relay module available in the professional home automation market. Packing 32 relay outputs and 32 digital inputs into one compact DIN rail device — each output rated at 10A NO/NC — the MS-B032 enables integrators to control an entire large residence or commercial floor from a single module, dramatically simplifying panel design and reducing installation time and cost.

The MS-B032 integrates natively via TCP/IP with Control4, Savant, Crestron, RTI, Nice, Hubitat, and Home Assistant. All drivers are included at no cost. The Control4 driver is officially certified, making it a premier choice for Control4 dealers tackling large-scale lighting, HVAC, access, or utility control projects requiring maximum I/O density from a single integration point.

Onboard configuration is fully self-contained: a built-in web interface and dedicated Access Point (AP) allow complete setup without external software or network infrastructure. The module supports native scheduling, on-device scene creation, and a hardware watchdog for autonomous fault recovery. API TCP/HTTP and MQTT provide maximum protocol flexibility for custom and hybrid integrations.

With two independent, monitored 12VDC power inputs, the MS-B032 maintains operation even if one power source fails — a critical requirement for estate-level and commercial deployments where reliability expectations are absolute. FCC and UL certified for the United States market. Manufactured in Brazil.

The MolSmart native app (iOS and Android) enables direct standalone control without any automation controller, making the MS-B032 equally versatile in projects of any complexity. Amazon Alexa voice integration is supported out of the box.
