NOTE:
When using LMB(X)24-SR… actuators, only use accessories listed on this page.
Typical Specification
Proportional control damper actuators shall be electronic direct-coupled type,
which require no crank arm and linkage and be capable of direct mounting to a
shaft from 1/4” to 5/8”. Shafts up to 3/4” diameter can be accommodate with an
accessory clamp. Actuators 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. Actuators shall have brushless DC motor
technology and be protected from overload at all angles of rotation. Actuators shall
have reversing switch and manual override on the cover. If required, actuator will be
provided with screw terminal strip for electrical connections (LMB24-SR-T). Run time
shall be constant and independent of torque. A 2 to 10 VDC feedback signal shall be
provided for position indication. Actuators shall be cULus listed, have a 5-year war-
ranty, and be manufactured under ISO 9001 International Quality Control Standards.
A
Actuators shall be as manufactured by Belimo.
LMB(X)24-SR(-T)
Proportional, Non-Spring Return, 24 V, for 2 to 10 VDC or 4 to 20 mA
Wiring Diagrams
1
Provide overload protection and disconnect as required.
2
CAUTION
Equipment Damage!
Actuators may be connected in parallel.
Power consumption and input impedance must be observed.
3
Actuators may also be powered by 24 VDC.
5
Only connect common to neg. (–) leg of control circuits.
The ZG-R01 500
Ω
resistor converts the 4 to 20 mA control signal to
2 to 10 VDC, up to 2 actuators may be connected in parallel.
WARNING
Live Electrical Components!
G
During installation, testing, servicing and troubleshooting of this product, it may be
necessary to work with live electrical components. Have a qualifi ed licensed electrician or other
individual who has been properly trained in handling live electrical components perform these
tasks. Failure to follow all electrical safety precautions when exposed to live electrical compo-
nents could result in death or serious injury.
