Optimized Detector (OD)

  • Sale
  • $ 5

For non-DCC applications. The OD is a small card that senses current flow in a section of track to determine block occupancy. The output of the card can drive LEDs or relays directly but most importantly connects directly to a line on an input card. A built-in potentiometer and test LED are used to adjust the circuit's sensitivity. Typically during normal operation, a dampened finger placed across the track will register as occupied.

Note: The quoted prices for all circuit boards provided by JLC Enterprises are for the fabricated boards only, that is, without any electronic parts. All circuit boards come unassembled and less components. All holes are drilled and all circuit traces are tin plated for easy soldering. Where double-sided boards are provided, all feed through holes are plated-through. The SMINI, SUSIC, RS485, DIN32, DOUT32 and PGCC boards have solder masking on both sides, silk screen legend on component side and are factory tested against shorts and open circuits.
