EZ-Occ-Quad

This compact occupancy detector board provides 4 optically isolated inputs for use on your layout. Each circuit can handle up to 4A of current and the board isolates each of those circuits from all other electronics on the board, making this a safe way to identify train location in a block. Furthermore the design automatically works to eliminate any jitter or bouncing of a signal due to dirt on wheels or track and requires no adjustments whatsoever.

The EZ-Occ-Quad supports metal wheelsets that have been fitted with resistors and is a reliable way to detect the presence of a train in the specified block. Typical values for resistors is 10K (10,000 Ohms) although other values can be supported.
