PECO Smartfrog - PLS-130

The Smartfrog automatically changes the electrical polarity of the turnout's frog when the turnout is operated, preventing short circuits and ensuring smooth train operation.

Yes, the Smartfrog PLS-130 is designed to integrate with and requires the PECO Smartswitch system to function correctly.

The Smartfrog is designed for PECO turnouts compatible with the Smartswitch system. Adapting it to other brands may require significant modification and is not recommended.

Refer to the PECO Shows You How booklet No. 24, 'Operating Points and Signals,' for detailed wiring diagrams and instructions specific to the Smartswitch system.

Changing frog polarity ensures that the running rails of the turnout are correctly aligned electrically with the frog. This prevents short circuits, especially with locomotives that have power pickups on both bogies, and avoids derailments caused by electrical faults.

While the Smartfrog itself manages frog polarity, it is part of the Smartswitch system which can be used to operate turnouts, semaphore signals, level crossing gates, and other moving features. The Smartfrog specifically addresses the electrical aspect of turnouts.

You can use a Smartfrog for every turnout that requires automatic frog polarity switching and is operated by the Smartswitch system. The number is limited by the capacity and wiring of your Smartswitch system.

Verify that the Smartfrog is correctly wired to the turnout frog and the Smartswitch system. Ensure the frog polarity is changing as expected when the turnout is operated. Check for any stray wires or debris causing a bridge.

Confirm that the Smartfrog is properly connected to the Smartswitch system and receiving power. Check all wiring connections between the Smartfrog, turnout, and the Smartswitch controller.

Double-check the wiring of the Smartfrog to the Smartswitch system. Refer to the wiring diagrams in the PECO booklet for correct polarity connections. Ensure the Smartswitch system itself is functioning correctly.
