Track Signal Wiring Diagram Dc - The switch shown on the right of the diagram is the red or green power feed that is received from the existing wiring configuration. When the signal is set to red, power is sent via the other diode straight to the red signal, bypassing the relay control altogether.. However, instead of the analog system's direct current (DC) to the track, in a digital control system, the red and brown wires carry the digital track signal. Instead of manual control boxes, the blue wires are connected to digital decoders that control turnouts and signals.. CAMTECH/S/2004/DCTC/2.0 3 D.C. Track Circuit – Ver 2.0 March 2004 ♦ Ballast shall be kept clean throughout the track circuited section should be taken do.

The signals can either be wired to conventional switches and supplied by 12-15 volts DC or a 9V battery (resistors supplied) or controlled by DCC via a DCC signal controller / decoder like the Train-Tech SC1/SC2 or other third party DCC decoders from Hornby, ESU, Lenz, NCE etc.. • Determine maximum current for Switch Machines, Signals & Building Lights. • 4) Divide the total current by the booster current rating to figure out the number of boosters you will need.. Track wiring capacitance can cause a NCE BD-20 to indicate that the track is occupied, when it is not. A capacitor, connected as shown here, can compensate for the capacitance of the track wiring, and allow the BD-20 to operate normally..

ACI biased DC track relay QBAT 2F.2B 1.75 v 9 ohms up to 750 mtrs. 11 K.50 Relays (METAL TO METALPLUG IN RELAYS) This relay comes in category of proved type relay. manufactured by Siemens’ India Limited under code K.50 Special Features: 1.. The procedure is roughly the same for wiring bi-color LEDs for Type SA signals. Remember that the center lead is the cathode, and color code the red and green wires for ease in installing the signal later.. EQUIPMENT REQUIRED: 12 volt power supply, volt-ohmmeter, DC ammeter and 2 test speakers 1. Connect negative ohmmeter lead AND power supply negative lead to unit chassis (ground)..

• Dual head signals are often located ahead of a track switch where the diverging track is a non-signaled siding or branch line. When the switch is lined for the main track, the upper head indicates the condition of the main route (straight) past the switch, and the lower head indicates red..
