ATOM DCC Block Detector (C/MRI Compatible)
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).
- Isolated, current-transformer based detection for DCC
- Highly sensitive (~1mA, equivalent to a 10k ohms)
- Simple single button sensitivity adjustment
