TAF24 (-S) Typical Specification
On-off spring return damper actuators shall be direct coupled
type which require no crankarm and linkage and be capable
of direct mounting to a jackshaft up to a 1.05” diameter. The
actuators must be designed so that they may be used for
either clockwise or counterclockwise fail-safe operation.
Actuators shall have a manual positioning mechanism
accessible on its cover. Actuators shall use a brushless DC
motor and be protected from overload at all angles of rotation.
Run time shall be constant and independent of torque. If
required, 2 SPDT auxiliary switches shall be provided with
one switch having the capability of being adjustable. Actuators
with switches must be constructed to meet the requirement for
double insulation so an electrical ground connection is not
required to meet agency listings. Actuators are UL listed and
CSA certified, and be manufactured under ISO 9001
International Quality Control Standards. Actuators shall be
as manufactured by Belimo.

Actuator may also be powered by 24 VDC.
Actuators with plenum rated cable do not have
numbers on wires; use color codes instead.
Actuators with appliance cables use numbers.
APPLICATION NOTES
Meets cULus or UL and CSA requirements without
the need of an electrical ground connection.
Equipment damage!
Actuators may be connected in parallel. Power con-
sumption and input impedance must be observed.
