Reverse-Loop Module with short-circuit protected reversal polarity via Sensor Tracks for digital operation (all formats) from the Digital-Professional-Series !

Features of the KSM-SG

  • The polarity reversal of the Reverse-Loop will be carried out without short circuit via 2 sensor tracks at the entrance and at the exit of the Reverse-Loop.

  • Both rails of the sensor tracks (A1/B1 and A2/B2) and the Reverse-Loop (AK/BK) will be completely isolated and connected to the respective marked clamps at the Reverse-Loop Module KSM-SG.
  • The optimal length of the sensor tracks will be 5 to 20cm.
  • The minimum length of the reverse-loop track has to be as long as the longest train on the layout.
  • The Reverse-Loop Module KSM-SG can switch up to 8 Ampere digital current.
  • With reason to an external power supply possibility is a simple control of the reverse-loop with track occupancy module (e.g. RM-GB-8-N or RS-8) possible. The sensor tracks will be controlled as well.

The Reverse-Loop Module KSM-SG from the Digital-Professional-Series can be operated without any problem on your digital controlled layout.

The finished module and the finished module in a case comes with a 24 month warranty.

Each Reverse-Loop Module KSM-SG will be supplied with a detailed operating-/respectively assembly-instruction. Those instructions can be found within the next section.

You can purchase the KSM-SG as a kit (-B), as tested finished module (-F) or as tested finished module in a case (-G).
