AR-2 Automatic Reverse Circuit with Adjustable Delay

AR-2 Automatic Reverse Circuit with Adjustable Delay

Details:

The CIRCUITRON AR-2 is a sophisticated integrated circuit automatic polarity reverser designed for point-to-point layouts in any model railway scale. It provides reliable 5 amp reversing capability while adding advanced operational control through an adjustable time delay system, allowing realistic shuttle-style train operation between reversing sections.

Unlike basic reversers, the AR-2 can pause a train at each end of the layout before automatically reversing direction. The delay is fully adjustable from 0 to over 1 minute, enabling flexible operating sessions ranging from rapid shuttle movement to realistic timetable-based stopping.

The AR-2 includes a dedicated external activation terminal that allows the time delay circuit to be triggered without reversing direction. This can be connected to a panel pushbutton or integrated with CIRCUITRON detection systems for automated control at specific points on the layout.

When used with a CIRCUITRON DT-4 Rolling Stock Detector, the AR-2 can support up to four intermediate stopping points between end reversing sections, making it ideal for shuttle services, trolley systems, or complex switching operations. This enables realistic multi-stop movement patterns across a single line.
