Description
The Belimo SF24A-MOD is a heavy-duty, non-spring-return direct-coupled damper actuator engineered for demanding commercial HVAC applications where intelligent building automation system (BAS) integration is essential. Powered by a 24V AC/DC supply and delivering a robust 180 in-lb torque output, this actuator is built to drive large dampers with confidence and precision.
Equipped with Modbus RTU communication, the SF24A-MOD enables seamless two-way digital communication with building automation controllers, allowing operators to monitor actuator position, set point, and operational status in real time. This makes it an ideal choice for VAV systems, air handling units, and other critical HVAC applications where data-driven control and diagnostics are required.
