accessories listed on this page.
For actuator wiring information and diagrams, refer to Belimo Wiring Guide.
Typical Specification
Spring return control damper actuators shall be direct coupled type which require no
crank arm 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 500Ω 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. Actuators shall be
cULus Approved and have a 5 year warranty, and be manufactured under ISO 9001
International Quality Control Standards. Actuators shall be as manufactured by Belimo.
Wiring Diagrams
Provide overload protection and disconnect as required.

CAUTION Equipment Damage!
2
Actuators may be connected in parallel.
Power consumption and input impedance must be observed.
Up to 4 actuators may be connected in parallel if not mechanically mounted
to the same shaft. With 4 actuators wired to one 500 Ω resistor.
2
Power consumption must be observed.
Actuator may also be powered by 24 VDC.

For end position indication, interlock control, fan startup, etc., AFB24-SR-S
4
and AFX24-SR-S incorporates two built-in auxiliary switches: 2 x SPDT, 3A
(0.5A) @250 VAC, UL Approved, one switch is fi xed at +10°, one is adjust-
able 10° to 90°.
Only connect common to neg. (–) leg of control circuits
5
The ZG-R01 500 Ω resistor converts the 4 to 20 mA control signal to
2 to 10 VDC.
ATTENTION:
AFB24-SR(-S) and AFX24-SR(-S) cannot be tandem mounted on
the same damper or valve shaft. Only On/Off and MFT AF models can be used for
tandem mount applications.
