LB101 Block Occupancy Detector

LB101 reports occupancy status in track sections to the encoder LR101. It operates on the so called "current sensing principle", that is there is always a feedback when a current user is in the monitored track section (detection section).

Connecting LB101 to booster and encoder

The LB101 taps into the power feeds to the track. The power supplying the track goes from LV100 via LB101 to the track. That way LB101 is able to detect current changes.


Illustration 1 shows the connection of LB101 to LV100 and LR101. The connections from LV100 via LB101 to the track are black, the connections between LB101 and LR101 are shown in gray.

The circuit from connector "J" on LV100 to the common rail remains, or is set up using one of the free connectors J on LB101. For ease in wiring, there are two connector J on each occupancy decoder.

Connectors O and ^ are intended for connecting to encoder LR101. Wire connector ^ to the corresponding connector on LR101, and connector O with one of the occupancy decoder inputs on LR101. You can connect a total of 4 LB101 to one LR101. That equals 8 detection sections. If you want more detection sections on your train layout, simply add another set of LR101/LB101s.

Important note:

Never connect the ^ inputs of different LR101s to each other.
