TGMB
TGMB24-SR
Proportional Control, Non-Spring Return, Direct Coupled, 24V, for 2 to 10 VDC and 4 to 20 mA
TGMB24-SR - Typical Specification:
Proportional control damper actuators shall be electronic
direct-coupled type, which require no crankarm and linkage
and be capable of direct mounting to a shaft up to 1.05”
diameter. 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. Run
time shall be constant and independent of torque. A 2 to
10 VDC feedback signal shall be provided for position
indication. Actuators are cULus listed, and be
manufactured under ISO 9001 International Quality Control
Standards. Actuators shall be as manufactured by Belimo.

WARNING
Live Electrical Components!
During installation, testing, servicing and troubleshooting of this product, it maybe
necessary to work with live electrical components. Have a qualified 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 components could result in death or serious injury.

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.
