Carlo Gavazzi's loop detectors for either single or dual loops are available in either plug-in or DIN rail mount housings. Loop detectors are installed for use in parking lots, streets, tool gantries, traffic light control and other places. The LDD (DIN Rail) and LDP (Plug) Series come with universal supply voltage and are in highly compact size.
The LDD and LDP loop detectors are equipped with automatic loop frequency tuning and sensitivity tuning to provide easy installation. Automatic sensitivity boost (ASB) helps detection of high bed vehicles such as trucks or busses. Other features include DIN rail and Plug in types, 20µH to 1000µH loop input inductance, multicolor diagnostics LEDs, fail safe and fail secure functions, two SPDT relay outputs, selectable output operation, power supply range 24-240 VAC/DC, sensitivity adjustment, automatic or manual loop frequency tuning, loop diagnostics capabilities to detect loop short/open circuit, inductance out of range and channel cross talk.
