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 screw terminals for the power and output connections.  For our friends invested in C/MRI, we offer an alternate version of the ATOM (part number CKT-BD1-CMRI) with a plug that connects directly into the C/MRI detector motherboard and provides a drop-in replacement for the DCCOD.

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

Typical Applications

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