DLD-2, Directional Logic Device

Product Type: Directional Logic

This directional logic device supplies the direction that a vehicle is going by using two detectors connected to two loops. Using this approach, one simply connects the relay outputs from the two vehicle detectors to the DLD-2’s inputs and the unit takes it from there. It carefully measures the inputs and determines the direction the vehicle is moving.

Adds yet another new dimension of simplicity to the industry
No switches to set, no buttons to push, no questions to ask.
Replaces a boxful of relays to generate the required logic

Power: 10 to 30 volts AC or DC, 3 mA typical

Power Indicator: The green LED is the power indicator. If power is within the stated limits, the green power LED should be on steady.

Directional Indicator: This LED, located on the right side of the front panel, is bi-color – green, red, or off. When the A loop is entered first, the LED will blink with a green indication until the B loop is entered. It then turns a solid green. If the B loop is entered first, then the LED will blink with a red indication until the A loop is entered. It then turns a solid red. When the loops are both cleared, this LED will be dark.
