TAF24-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 jackshaft up to a 1.05” diameter. 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 counter-
clockwise fail-safe operation. Actuators shall have control direction of
rotation switch accessible on its cover. 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.

Actuator may also be powered by 24 VDC.
Only connect common to neg. (—) leg of
control circuits
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.
