TLF24 (-S)
On-off, Spring Return Fail-Safe, 24 V
Torque min. 35 in-lb, for control of air dampers
Application
For on-off, fail-safe control of dampers in HVAC systems.
Actuator sizing should be done in accordance with the damper
manufacturer’s specifications. Control is on-off from an
auxiliary contact, digital output, or a manual switch.
The actuator is mounted directly to a damper shaft from 3/8”
up to 1/2” in diameter by means of its universal clamp, 1/2”
shaft centered at delivery. For shafts up to 3/4” use K6-1
accessory. A crank arm and several mounting brackets are
available for applications where the actuator cannot be direct
coupled to the damper shaft.
Operation
The TLF series actuators provide true spring return operation
for reliable fail-safe application and positive close off on air tight
dampers. The spring return system provides consistent torque
to the damper with, and without, power applied to the actuator.
The TLF series provides 95° of rotation and is provided with a
graduated position indicator showing 0° to 95°. The actuator
may be stalled anywhere in its normal rotation without the
need of mechanical end switches. Power consumption is
reduced in holding mode.
The TLF24-S version is provided with one built in auxiliary
switch. This SPDT switch is provided for safety interfacing or
signaling, for example, for fan start-up. The switching function
is adjustable between 0° and 95°. The auxiliary switch in the
TLF24-S is double insulated so an electrical ground
connection is not necessary.
For all accessories, see pages 110 and 132.
