Nice Loop Detector
LP21 series Traffic Detectors are electronic sensors for inductive recording of metallic objects. Vehicles, and depending on the device also their model and the direction of movement, can be detected via up to two induction loops. Traffic detectors are operated in combination with a wide variety of induction loops and control systems, such as frequency converters and PLC control systems. Areas of application may be facilities in the traffic engineering, door and barrier control, or parking and tunnel surveillance sectors. The LP21 Traffic Detector is intended for installation in a control cabinet or a housing similar to a control cabinet.
Features:
– 1 loop channel (LP21)
– 2 potential-free relay outputs
– 1 connection for power supply (24 volt AC/DC)
– 1 USB interface for diagnostics and expanded configuration
– 8-pole DIP switch for configuration
– LEDs to indicate detector and loop status
– Compact plastic housing for mounting on DIN rail in controller cabinet
– Galvanic isolation between loops and electronics
– Automatic adjustment of the system after activation
– Continuous readjustment of frequency drifts to suppress environmental influences
– Sensitivity independent of loop inductivity
– Fixed signal hold times independent of the coverage rate of the loops
