AC220V TLD-600 Four Relay Vehicle Loop Detector With Exit Pulse Direction Detection
Model No. TLD-600
1.Introduction
TLD600 is used for wherever vehicles have to be detected, for example for monitoring and safe guarding access ways or for counting vehicles. The output signal can be used for controlling door drive mechanisms, operating barriers, activating card dispensers etc.

Double loop detector TLD-600 panel
a. Tune
The tuning range is from 50µH to 1000µH, and such wide tuning range ensures low requirements for the loop and wiring. Any inductance changes will feedback to the compensation circuit in detector to ensure normal work.
b. Adjustable sensitivity
When in low sensitivity, the detector will detect vehicles with high chassis or trailers correctly except cars, bicycles and other small metals. The sensitivity adjust button is the rotary encoder switch on the panel, "0" with low sensitivity and "9" with high sensitivity. The A switch on left is corresponding to loop A, while B on right is corresponding to loop B.
c. Reaction time
Its definition is the time starting from the metal enters into the loop and ending when the detector gives indication signals.
