PLD32

The 2-channel circuit board detector PLD32 was designed for vehicle access control for door, gate, and barrier, for vehicle detection depending on traffic direction and for safeguarding and monitoring e.g. of conveyor systems and car-wash plants.

FUNCTIONAL DESCRIPTION:

The induction loop detector PLD32 analyzes the loops in the ground, working as inductivities of a high frequency oscillating circuit. The metal body of a vehicle passing the loop causes a characteristic change of circuit frequency. The loop detector analyzes it and sends a switching signal to the potential free relay output. This is also displayed at the front panel LEDs.
The loop signals are analyzed by a microprocessor. When the detector is switched-on an automatic alignment with the connected inductive loop is executed.
 

There is no interference of loop signals since the dual-channel version PLD32 analyzes the loops in a defined order (multiplex mode) so that only one loop is active at one time.

Via rotary and DIP switches on the front the detector can be comfortably set or via serial interface on the front of the device all current parameter and diagnosis values can also be set and readout.

This is done by means of the LoopMasteroperating program which is available free of charge and which additionally offers extensive loop and detector analysis functions. The trend-setting customizing allows an individual configuration and setting of operating elements and functions.
