The TD916/908HS is specifically designed as a traffic detector and has customised performance characteristics which make it ideal for road vehicle detection. The TD916HS is a 16-channel microprocessor-based vehicle detector, incorporating the requirements of the ANSI/NEMA Standard TS1, Part 15 (1989), where the TD908HS is the 8-channel equivalent of the TD916HS with the same form factor. The function of the detector is to detect vehicle presence by means of an inductance change caused by the vehicle passing over a loop buried in the road surface. The detector is designed for the ease of installation and operating parameters can be individually set for each channel by a command sent via a CAN Bus communications link available on the 96 way DIN41612 connector.
