- Occupancy detector 8, "Diode"
New year and new beginnings. We are processing orders from the Christmas holidays and right now we are 1-2 weeks behind. Longer on some items that are temporarily out of stock.
Important - US shipping!
Due to new US import taxes, it's currently a bit confusing about what applies and what the tariffs are.
The Swedish Postal service has launched a new small package delivery to US and we are testing it, but to use this service the US import tax must be charged in advance.
For UPS and FedEx shipping services, the shipping company bills the recipient for the import tax + an additional service charge.
Occupancy detector 8, "Diode"
Detector
Cards that senses the presence of a train on the track by the train's current consumption.
The card is connected to the track from one of the 8 outputs marked "A".
Both sides of the track feed should be connected to the input terminal marked "A" and "B".
The card works by detecting a voltage drop over a diode on the card. The voltage drop will be around 0.3 volt.
The card will use current from the track for its own need and will not need any additional current supply.
The card is isolated from the decoder side through opto-couplers.
8 track can be detected by one card.
The outputs on the card is connected to the inputs of the switch decoders or the signal decoders.
The sensitivity is high and around 0.3 mA can be sensed.
Outputs to the decoder is of the type "Open collector".
