Quad DCC Occupancy Detector – OD-OC1
Olin’s Depot OC1
The OC1 is a four-segment DCC block occupancy detector. It is completely powered from DCC, and provides four optically-isolated outputs with a common ground. The advanced microcontroller design allows for previously unavailable occupancy detection features, including compensating for the unoccupied current level and easy sensitivity setting in small calibrated steps. A single axle with a 10 kΩ resistor between the wheels can be reliably detected.
