Dual Auto-Sense "Smart" Block Occupancy Detector

NO TARIFFS for our USA customers!

Ultra Sensitive Block Detection

Specifically designed to detect rolling stock fixed with resistor wheel sets.

• Each detector PCB will monitor two separate DCC blocks.
• Will reliably detect up to 47K Ohm resistors across rails. *
• Proven Tuned-Coil Front End Design.
• Two Isolated Outputs per Block.
• Automatically sets sensitivity on each block.
• Tuned coil front end followed by precision rectifier, amplifier, and CPU.
• Serial port available for fine-tuning digital filter parameters.
• Requires input of 7-12VDC

*47K based on 1 meter clean track. Snowball Creek recommends industry standard values of 22K or 39K resistor wheelsets.
