TTF24-3
On-off, Spring Return Fail-Safe, Reversible, Floating Point, 24V
TF24-3 Typical Specification
Floating point, 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 shaft up to a 1/2” diameter and center a 1/2”
shaft. The actuators must be designed so that they may be used for
either clockwise or counterclockwise fail-safe operation. Actuators
shall have an external direction of rotation switch to reverse control
logic. 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. Actuators are cULus listed 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.
For triac sink the common connection from the actuator must
be connected to the Hot connection of the controller. The
actuator must be connected to the control board common.
APPLICATION NOTES
Meets cULus or UL and CSA requirements without the need
of an electrical ground connection.
CAUTION
2
Equipment damage!
Actuators may be connected in parallel.
Power consumption must be observed and input
impedance must be observed.
