2 to 10 VDC control of TTF24-SR
TTF24-SR
Proportional damper actuator, Spring Return Fail-Safe, 24 V for 2 to 10 VDC, or 4 to 20 mA Control Signal.
TTF24-SR Typical Specification
Spring return control 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 actuator must provide proportional damper control
in response to a 2 to 10 VDC or, with the addition of a 500
Ω
resistor, a 4 to 20 mA control input from an electronic controller
or positioner. The actuators must be designed so that they may
be used for either clockwise or counterclockwise fail-safe
operation. Actuators use a brushless DC motor controlled by a
microprocessor and be protected from overload at all angles of
rotation. Run time are 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.

Equipment damage!
Up to 4 actuators may be connected in parallel.
With 4 actuators wired to one 500
Ω
resistor.
Power consumption must be observed and input
impedance must be observed.
APPLICATION NOTES
Meets cULus or UL and CSA requirements without
the need of an electrical ground connection.
The ZG-R01 500
Ω
resistor converts the 4 to 20 mA
control signal to 2 to 10 VDC.

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.
Only connect common to neg. (—) leg of control
circuits.
