LM24… on-off - Typical Specification:
Control damper actuators shall be electronic direct coupled
type which require no crank arm and linkage. Actuators shall
be UL and CSA listed, have a 5 year warranty, and be man-
ufactured under ISO 9001 International Quality Control
Standards. Actuators shall have reversing switch and manual
override on the cover, and be protected from overload at all
angles of rotation. If required, actuator will be provided with
screw terminal strip for electrical connections (LM24-3-T US
and LM24-3-5P0-T US). If required, one adjustable SPDT aux-
iliary switch shall be provided (LM24-S US). If required, actua-
tors shall be provided with a built-in 5 kΩ feedback potentiome-
ter (LM24-3-5P0-T US) for use in modulating (floating point)
applications. Actuators shall be as manufactured by Belimo.
