DESIGN AND FUNCTION
The IR-projector features sealed cover. The board with 8 high-power IR-emitters with focusing lenses
and photo-relay designed for automatic switching-on of the emitters when the outdoor lighting decreases to 3
lx minimum is located at the front of the projector behind the shock-resistant glass. Earthing bolt and two
threaded openings M20x1,5 for cable-gland installation are located on the back cover of the IR-projector
from the outside. Cable glands ensure tight connection for circular section cables with outer diameter or
wrapping insulation (for armored cable) diameter from 8 to 10 mm.
It is recommended to use stainless-steel
cable glands for IR-projector in stainless-steel body. It is recommended to use cable glands made from
galvanized low-carbon steel for IR-projector in the body made from galvanized low-carbon steel.
Switching board with terminal boxes used for power cable connection is located on the back cover of
the IR-projector from the inside. Loop power supply for board with IR-emitters is connected to the switching
board.
Silica gel is placed into IR-projector body for moisture absorption.
IR-projectors Relion-TKV-300-M-IK and Relion-TKV-300-N-IK feature the same dimensions and
differ by the body material only. The projectors are fixed on mounting and positioning device by two fixing
clamps made from stainless-steel.
Design features of the IR-projector Relion-TKV-300-A-IK. Base of the mounting and positioning
device is fastened on the projector body by four bolts M6.
Overall dimensions of Relion-TKV-300-A-IK differ from dimensions of Relion-TKV-300-M-IK and
Relion-TKV-300-N-IK.
