Carlo Gavazzi LDD2PA2DU24 - Loop Detector - DIN Rail Housing - Dual Loop - Potentiometer - Adjustment - 2 x SPDT Outputs - Power Supply 24-240 VAC/VDC

Description
LDD 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

Main features
• 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

Main functions
• Opening and closing of barriers in a carpark. Output from loop detector can also be used to activate ticket machine and occupancy counting.
• Activation of bollards on the streets and any premise entrances/exits.
• Detecting vehicles at traffic light, tolls gantry and others.
• Directional logic to determine vehicle direction.
• Automatic Sensitivity Boost (ASB) function to detect high bed vehicles on the roads or in factories.
• Lighting activation in the car porch, carpark ramps and others.
