Product Description

Two-way output relays

Two outputs of them are unlimited when the corresponding loop is permanently covered, while the others are multi-mode that can be set by users

Direction detecting function can be used to statistics the vehicle flux

Principle is based on a change in the inductance within the loop which is caused by the metallic components of passing vehicles

Changes are picked up and evaluated by microprocessor

Ease of use due to automatic calibration when the operating voltage is applied
