TLF24-SR
Proportional Damper Actuator, Spring Return Fail-Safe, 24 V for 2 to 10 VDC, or 4 to 20 mA Control Signal.
Output Signal of 2 to 10 VDC for Position Indication.
TLF24-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 3/4” 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 shall use a
brushless DC motor controlled by a microprocessor and be
protected from overload at all angles of rotation. Run time
shall be constant, and independent of torque. A 2 to 10 VDC
feedback signal shall be provided for position feedback or
master-slave applications. Actuators are UL listed and CSA
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. The TLF24-SR wire 5 is white.
