Classification Detector for Din-Rail Mounting

MC3224 DETECTOR Classification Detector for Din-Rail Mounting

The MC3224 loop detector was specifically designed for vehicle detection with classification and speed measurement for traffic data acquisition and traffic management. The detector is designed for DIN-rail mount and includes a complete overvoltage protection module for the inductive loops.


The detector now offers the functions and outstanding features of the SWARCO TRAFFIC SYSTEMS classification detectors in 19" plug in technology also in a DIN rail mount version. Based on the proven and tested MC2224 and the certified CD9054, it includes a complete overvoltage protection module. This integration minimizes the wiring effort and significantly reduces the required space.

The MC3224 classifies the vehicles in (8+1), (5+1) or 2 classes
acc. to TLS*. The classification is not influenced by e.g. weather conditions. On activation of the directional logic, reports of wrong way drivers can be generated. The vehicle type is determined by means of passing-curves which have characteristic features depending on the different classes and the loop types used.

*TLS: Technical delivery terms for roadway stations

Via the RS485 bus single-vehicle data is transferred to a controller, which takes over further data aggregation acc. to TLS-specifications. The detector automatically adjusts itself to the attached loop/feed-cable combination. Variations in temperature have no influence on data acquisition.

The measuring systems are permanently checked for short or open loops, only when a definite malfunction is detected, systems are put into a failure condition. If one loop of a TLS double-loop system is disturbed, the remaining loop supplies further data on time of occupancy, time gap and a classification of car-similar and HGV-similar vehicles.

Speeds and vehicle lengths cannot be determined. Short measuring intervals and a new procedure for speed measurement provide for the high accuracy of the measured data and the high detection speed, according to the requirements of the German federal highway research institute.

The LoopMaster operating program, which is available free of charge, offers extensive loop and detector analysis functions. The trend-setting customizing allows an individual configuration and setting of operating elements and functions.

The detector can provide the following single-vehicle data via the RS485 interface, depending on the TLS classification version:
