The IR4 infrared train detection controller allows detection of model trains at specific points on the track.
The IR4 is an infrared train detection controller. Model trains can be detected at points on the track using infrared light. Up to four IRSB infrared sensors can be operated with the IR4.
The IR4 provides four open-collector detection outputs.
Sensors can be programmed to operate the same outputs, this is useful when multiple sensors define one block.
