Tams Elektronik 49-01136-01 KSM-3 Turnback Loop Module for Digital Layouts, Ready-to-Use Module

Are you looking for a reliable solution for turnback loops on your digital model railroad layout? The Tams Elektronik 49-01136-01 KSM-3 Turnback Loop Module is a pre-assembled and tested ready-to-use module for digital layouts and is suitable for all scale sizes.

In turn loops in particular, track sections with different polarities meet both inside and outside the loop. The KSM-3 detects the voltage drop as soon as a short circuit is about to occur and reverses the polarity within a few milliseconds before the voltage drops completely.

Low-short-circuit-risk turnback loop module for digital operation

The module is not completely short-circuit-free, but it has a low short-circuit risk. This ensures a smooth passage over the separation point while effectively protecting wheels, pantographs, and rails.

The threshold value for the polarity change is set individually via a trimmer potentiometer. An LED assists with precise adjustment and lights up as soon as the appropriate threshold value for the respective layout is reached.

Integrated Circuit for the Entry and Exit Turnouts

The KSM-3 features an additional output for connecting a turnout with a dual-coil drive. The turnout is automatically switched as soon as the locomotive reaches one of the two separation points. At the same time, the polarity changes within the turnaround loop.

For motor-driven turnouts, the AMW-1 motorized turnout adapter is also required. Because the breakpoints are permanently assigned to the correct turnout position, the sequence remains reliable even if the turnout has been adjusted externally.

Also suitable for turntables and complex layouts

The KSM-3 can also be used with turntables. In this case, the bridge is connected like the inner section of a turning loop to compensate for different polarities at the transitions.

Advanced layout concepts with storage tracks or a shadow station are also possible. Get the Tams Elektronik 49-01136-01 KSM-3 ready-to-use module and equip your digital model railroad layout with a well-designed solution for turnaround loops, turntables, and challenging track layouts.

• Integrated control of the entry and exit turnouts
• Additional output for connecting a turnout with a dual-coil drive
• For motor-driven turnouts, the AMW-1 motorized turnout adapter is also required

Procedure:

• Phase 1: Depending on the current switch position, the locomotive enters the turnaround loop from the left or right
• Phase 2: Upon entering the turnaround loop, the polarity within the loop is reversed—if necessary—upon reaching the breakpoint after the turnout
• Phase 3: When exiting the turnaround loop, the polarity within the loop is reversed upon reaching the breakpoint before the turnout, and at the same time, the turnout is set correctly for the train’s exit

Notes on layout planning:

• The inner section of the turnaround loop between the two separation points must be at least as long as the longest train that is to pass through the turnaround loop
• The circuit also functions when multiple trains are inside the turnaround loop at the same time
• This requires that the two separation points are not crossed simultaneously
• Branching tracks within the turnaround loop are possible
• The maximum current for all vehicles within the turnaround loop is 8 A
• This includes the locomotive’s motor current, car interior lighting, and other electrical loads
• The turnaround loop can be extended with a hidden station or storage tracks
