Sree Dhanam Automation Private Limited

LDP loop detector is well suited to be used in parking, drive through and car access control applications to control barriers, gates, bollards and car access equipment. Automatic frequency tuning and easy sensitivity adjustment enable easy setup and installation. Automatic sensitivity boost ensures high bed vehicles are detected reliably. Multicolor LED indication enables user to easily adjust loop inductance and intuitively indicate installation issues for easy diagnostic. Individually user-assigned relay mode for 2 x SPDT outputs enables easy adaptation to many applications. Directional logic in dual loop model can be used to ascertain vehicle direction.Loop input inductance: 20 μH to 1000 μH • Adjustable sensitivity in 10 steps: 0.01% to 1.00% via potentiometer • Automatic loop frequency tuning or manual tuning via 4 adjustable loop frequency channels to avoid crosstalk • Automatic Sensitivity Boost (ASB) for high bed vehicle detection • Selectable fail safe and fail secure mode • 2 x SPDT relay outputs, selectable operation as pulse or presence switching • Multicolor power/fault LED indication for easy setup and intuitive diagnostic • Individual loop state multicolor LED to indicate different loop status and fault. • Loop diagnostic capability: loop short circuit, loop open circuit, inductance out of range, channel crosstalk. • Directional logic for dual loop. • Wide range power supply: 24-240 VAC/VDC, 45-65 Hz (LDPxPA2DU24) and 12-36 VAC/VDC, 45-65 Hz (LDPxPA2DU12).
