Belimo Spring Return Fail-Safe, On/Off Damper Control Actuator, Direct Coupled - 24 VAC/DC

Features: Cut labor costs with (10 min. installation) simple direct coupling. Actuator Centers on 1/2" shaft (K6-1, 3/4" clamp optional). True mechanical spring return - the most reliable failsafe. Mount for clockwise or counterclockwise fail-safe. Easy-to-adjust mechanical stop to limit damper rotation. Check damper position easily with clear position indicator. Don't worry about actuator burn-out. Belimo is overload-proof throughout rotation. Need to change control direction? Do it easily with a simple switch (modulating actuators). Built-in auxiliary switch is easy to use, offers feedback or signal for additional device. Microprocessor-controlled brushless DC motor increases actuator life span and reliability, provides constant running time (modulating actuators). Provided on Basic Models Rugged metal housing withstands rough handling in the mechanical room. 3 ft. cable and conduit connector eases installation. The LF24-S is used for On/Off, fail-safe control of dampers in HVAC systems. Actuator sizing ...
