PART #: C4T-QBOD-AU We have designed a current-sensing occupancy detector that works with both DC and DCC layouts. Current sensing detection requires rolling stock to draw a small current. You can make your own detectable wheelsets for rolllng stock that draw a small current, or you can purchase them from companies such as Logic Rail Technologies We have had good results with two of their detectable wheelsets per car. Whether the output of a detector drives a signalling circuit or feeds into a computer, isolation between your track power and the circuit the detector feeds into is a good idea. Our detector accomplishes this by using optical isolation. To help keep costs down, our circuit board is designed to hold up to FOUR detectors. This way, the most expensive components (the board and the connectors) are shared across four detectors. This can also simplify your layout wiring, as a single feeder from your track bus is needed for four separatly detected sections of track. If you have a situation where you don't need all four detectors in a location, it is possible to only populate the part of the board for the circuits that are needed. Specifications Specifications for version 3 cards appear in the installation instructions available at the bottom of this page. Version: 4.00 Card size: 2.75" x 2.75" Mounting hole size: 0.125"Suitable for #4 screws Detectors per card: 4Card may be partially populated with 1, 2 or 3 detectors Maximum continuous track current: 4amperesHigh current (8A) option to be availabe Track connector: Screw terminal blocks2 terminals for power input feed, 1 for each blockEach terminal accepts14-22 gauge Output connectors: 6-pin SIP for outputs, ground, and power 2-position terminal block for power and ground4-position terminal block for outputs Output type: Open collectorCompatable with active low input devices, such as C/MRI and NCE AIU.
