Functional description
The 4-channel loop detector IG224/4 was especially designed for traffic applications and stands out for its
multitude of special functions. Like the series IG224 and IG224/2, loops are controlled in the noise immune
multiplex mode. Besides the usual switching outputs, this detector has a RS485 data-bus interface.

4-Channel-Loop-Detector
Card plug for rack system
The oscillator can be adjusted to very low loop inductivities by a jumper (single-turn loops). For inductivities
of 400 µH and more a resistance of 40 Ohm is permitted (corresponds to approx. 550 m feed cable with
∅ = 0.8 mm). The front-side service interface can be used to adjust via laptop (service software IGBT)
multiple channel parameters like: sensitivity, measuring time, hold time, operational frequency, switch on/off
delay, directional logic and oversampling.
The software is also designed for the diagnosis of loops and detectors, and for activating special functions.
Classification function
A bus detection can be implemented by using a special loop (10 m x 2.5 m, 2 windings). The value of
attenuation is the decisive criterion. For smaller loops (loop length: 1,0 m– 2,5 m) a simple differentiation
between car / lorry can be realised.
Synchronization
Crosstalk of loops and their feeder cable can be eliminated by synchronizing up to 30 detectors.
