This replaced the SB3a and now includes NCE's P514 five Amp, internationally approved power supply.
Everything you need to get started with Advanced Digitrax Command Control 8amp System.
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.
Operates just like a Stationary/Accessory Decoder, only it does not have a voltage output. Instead, it allows you to provide your own external voltage specific to your accessory just like you would do with a regular old fashioned toggle switch.
