ATOM DCC Block Detector (C/MRI Compatible)

   

CKT-BD1-CMRI


The Iowa Scaled Engineering ATOM is a reliable, easy-to-install, single-channel DCC block detector.  Compatible with a wide variety of other block detectors on the market, the ATOM provides two open collector outputs (one for detection, one for no detection) with optional pull-up resistors and easy pushbutton sensitivity adjustment.  Since it's based on a current transformer, the detector maintains isolation between your track and signal systems.

This version has a C/MRI-compatible connector attached instead of screw terminals.  This version is made especially for customers invested in the C/MRI system, and offers a Molex connector that plugs directly into the C/MRI detector motherboard.  It's a drop-in replacement for the DCCOD detectors.  If you're looking for the conventional screw terminals, please see the original ATOM (part number CKT-BD1).

Features

  • Isolated, current-transformer based detection for DCC
  • Highly sensitive (~1mA, equivalent to a 10k ohms)
  • Simple single button sensitivity adjustment
  • Two opposite polarity, open-collector outputs (40V / 250mA capable)
  • Optional built-in 10k output pull-up resistors
  • Powered from 5V to 24V
  • C/MRI compatible!  Plugs directly into the detector motherboard, just like the DCCOD

Typical Applications

  • Detect block occupancy for signal systems
  • Activate grade crossing signals
  • Trigger sounds
  • C/MRI track occupancy inputs
