TC-4 TORTOISE Direction Alternator

TC-4 TORTOISE Direction Alternator

Details:

The CIRCUITRON TC-4 Tortoise Direction Alternator is designed to provide alternating control of stall-motor turnout systems, operating in a similar way to the TC-2 but specifically configured for use with the Tortoise Slow Motion Switch Machine. Each activation of the control input reverses the turnout position, allowing automatic route selection and alternating train paths around a layout.

This makes the TC-4 ideal for continuous running loops, sequential routing, and automated layout operations where turnouts must switch direction each time a train is detected or a control signal is triggered.

The TC-4 operates with a single control input that toggles turnout position each time it is activated, reducing wiring complexity while enabling flexible route automation. It is well suited for layouts that require trains to alternate between multiple paths without manual intervention.

Although functionally equivalent to the TC-2 in logic, the TC-4 is specifically designed for stall-motor operation, providing smooth and reliable turnout movement when used with compatible mechanisms. It integrates easily into CIRCUITRON detection-based systems and can be used in both simple and advanced automated control panels.

The TC-4 requires a 12–18V DC power supply and is built on a compact printed circuit board for easy under-baseboard installation.
