Iowa Scaled Engineering - ATOM DCC Block Detector

ATOM DCC Block Detector 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 is 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 Specifications: 2.0(L) x 1.5(W) x 0.875(H) inches
