Belimo Spring Return Fail-Safe, On/Off Damper Control Actuator, Direct Coupled - 24 VAC/DC (No Aux Switch)

Features: Easy-to-adjust mechanical stop to limit damper rotation. Cut labor costs with simple direct coupling. Actuator Centers on 1/2" shaft. Clockwise or counterclockwise fail-safe mounting for fail-safe. Compact size with the shortest shaft-center to edge distance in the industry - 0.77". True mechanical spring return - the most reliable fail-safe. 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). Microprocessor-controlled brushless DC motor increases actuator life span and reliability, provides constant running time (modulating actuators). Rugged housing withstands rough handling in the mechanical room. 3 ft. standard cable and conduit connector (not shown) eases installation. For on/off, fail-safe control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer?s specificati...
