TC-1 Turnout Control Twin Coil

TC-1 Turnout Control Twin Coil

Details:

The CIRCUITRON TC-1 Turnout Control is designed to provide automatic operation of twin-coil switch machines when used with CIRCUITRON detection systems such as the DT-4. It is intended for advanced turnout automation, including non-derailing operation on trailing point turnouts, ensuring smooth and reliable routing of trains across complex layouts.

By using opto-sensor inputs placed on each approach to a turnout, the TC-1 can automatically detect an approaching train and align the points accordingly, preventing derailments and improving operational realism. It can also be configured for manual control via pushbuttons, providing full operational flexibility.

The TC-1 uses two input control terminals to “force” turnout direction based on detection inputs or manual commands. In a typical installation, opto-sensors are positioned on both legs of a turnout ahead of the frog. When a train is detected, the corresponding signal activates the TC-1, ensuring the turnout is correctly aligned for safe passage.

Manual pushbutton control can be added to maintain operator override capability. The unit is designed for fast response, with a recycle time of approximately 2 to 3 seconds, allowing frequent turnout operation in busy layout environments.

The TC-1 operates from a 12–18V AC or DC supply, with maximum performance achieved using 18V AC or unfiltered DC. It is constructed on a 3" square printed circuit board for straightforward installation in control panels or under-baseboard wiring systems.
