Tenet Vehicle Loop Detector PD-232 2 RELAYS in Parking Management System

Introduction:

The PD-232 is a dual channel microprocessor based detector designed specifically for  parking and vehicle access control applications.The primary function of the detector is  to detect vehicle presence by means of an inductance change caused by the vehicle passing over a wire loop buried under the road surface.

The various modes are selected by changing the position of switches on the front of the unit. The detector oscillator is multiplexed to eliminate any possibility of crosstalk between the loops connected to the detector. The switches allow for different loop frequency settings, sensitivity settings and modesettings.

The unit has a number of initial selectable options for configuration of relay outputs.

The PD-232 provides visual outputs ( LED ) on the front of the enclosure and relay  change-over contacts at the 11 pin connector at the rear of the enclosure. The power LED indicates that the unit has been powered. The channel status LED’s below indicate that a vehicle is present over the loop and when there is a fault on the loop. The Presence relays are normally fail secure and will close on a vehicle detect or loop failure but not if there is a power failure.
