How the TFB120 actuator works

The Belimo TFB120 is an on/off actuator with spring return that runs directly on line voltage from 100 to 240 Vac, so no control transformer is needed. With power applied, the damper drives to its powered position. When power is removed, the spring returns it to its fail-safe position. Power Open means spring close on power loss; Power Close means spring open on power loss. The end switch option provides a contact that proves the damper has reached position, for interlocking an exhaust fan or appliance.

HCR or HSI: which one do you need?

The HCR connects inline between two open duct ends, for new construction, remodels and any duct run being modified. The HSI slips into existing ductwork through a partial cut on one side only, so there is no need to remove a duct section or cut all four sides. The HSI is built slightly undersize so it slides inside the duct, and a 1" flange seats against the duct exterior. Order the interior duct dimension for either type, and call the factory if you are unsure how to measure.
