Priority circuit IR

With this set you can create a priority system for DC-Car vehicles.  Operation:

By means of the optional Hall sensor, IR sensor or reed contact which is mounted in the priority road, merging traffic or traffic from the other road is stopped via an IR LED that emits the DC-Car Stop command. An adjustable timer (1 sec - 20 sec) determined how long this movement remains stationary. The circuit operates with pulse extension which means that cars on the priority lane always extend the DC-Car stop signal. This signal is by means of the optional IR LED assigned to the traffic on the road.

The circuit works independently, and  generates the DC-Car Stop command itself. A computer or a function module is not needed.

For the triggering also a reed contacts can be used.

Specifications:

Operating voltage: 12 - 16V ~ / =

Input: Switches to GND (Reed / Hall contacts between GND and connect IN)

Output: IR DC Car Stop command (serial resistor for the IR LED is already on the board!)

Output: + 5Volt to power the Hall sensor (not suitable for powering other circuits!)

To the circuit, several Hall sensors may be connected in parallel so that, for example, also a T-junction can be arranged with opposite traffic.

The user manual you find here.

Other uses:

A narrowing of the road or construction site arrangement, hereby  the oncoming traffic is temporarily stopped. (two modules needed)

Taxi stand where taxis sets itself still a short time.
