Monitors & detects engines and rolling stock for 2 blocks
Provides 2 open collector outputs for each block.

Auto-Sense adjusts sensitivity for each block
Automatically measures baseline value, calculates detection threshold and stores these values for each block. Then uses the stored threshold each time it is powered on. Easily re-measure by pressing a button.

Ultra-sensitive detection
Will detect up to 47K resistor wheel-sets. This is the ultimate detector for rolling stock detection. Works well with industry standard values of 39K, 20K, or 10K resistor wheel-sets

Proven Tuned-Coil front end design
Utilizes proven Tuned-Coil front end design, followed by a precision rectifier circuit. The signal is then processed by a microprocessor to digitally filter and provide intelligence.

Easy to integrate into your layout
Needs only 1 turn of feeder wire through the coil. Open collector outputs can convey occupancy to virtually any type of digital input or indication. Easy screw terminals for all power and output connections. Includes 3 M3 mounting holes.

Requires 8-16VDC Power input
Use our 8VDC Power Tap (sold separately) to provide input and derive power from a wide variety of sources.
