STATION STOP

Published:2013/6/21 3:01:00 Author:muriel | Keyword: STATION STOP

This circuit will stop and start the train at a station located on the reversing track. This circuit is as simple as possible, using the bottom section of a 556 timer as a photodetector and the top section as the delay timer. The timing circuit takes its control and track power from the power supply circuit on this page. NOTE: When using this circuit, there are other things to consider, such as; train length and whether the locomotive has all wheel pickup. These can affect the placement of the gaps and phototransistors.   (View)

6 Aspect - Searchlight Signal Driver (LM555)

Published:2013/6/18 21:40:00 Author:muriel | Keyword: 6 Aspect, Searchlight Signal Driver , LM555

The circuit on this page is a 6 Aspect driver for a bicolour LED type Searchlight Signal. The available signal indications are; SOLID - RED, YELLOW, GREEN, and FLASHING - RED, YELLOW and GREEN. The circuit can also turn the signal OFF for approach lighting if desired. As this is a driver circuit, there is no actual input logic to select the signal indication. This will be added when it has been worked out. If you have any ideas on how such a logic system might function might work, please send an email with any details. The first circuit on this page is controlled by four toggle switches. Refer to the tables on the diagram for switch positions and the resulting signal indications.   (View)

Push Button Motor Control Circuits

Published:2013/6/18 3:56:00 Author:muriel | Keyword: Push Button, Motor, Control Circuits

The circuits on this page are for motor controls using Push buttons and would typically be found in commercial and industrial installations. The circuits do not show the wiring of the motors themselves as this depends on the particular motor type. The type of motor also governs the number of contacts needed for the motor side of these circuits. The Relay Holding Contacts and the Interlock Contacts shown in these circuit would normally be built into the motor control relays.   (View)
