Massoth 8157001 DiMAX® Reverse Loop Module (Replaces LGB 55080)
The Massoth DiMAX Reverse Loop Module ensures flawless operation in
reversing-loops and Wye-junctions. The module can handle digital track
currents of up to 15Amps without triggering a short-circuit.
Currently available products for operating
reversing-loops and Wye-junctions rely exclusively on short-circuit
detection, the Massoth DiMAX Reverse Loop Module offers additional
options as well.
With the included sensor-tracks installed, the module
operates without relying on short-circuit detection at all. The module
detects the polarization of the entering train and adjusts the polarity
of the reversing-loop section accordingly, before the train enters the
loop. Track contacts (reed switches) may be used instead of the supplied
sensor tracks; however, using track contacts requires the installation
of a magnet under each locomotive.
A mixed operation with sensor-tracks and short-circuit
detection is also possible; short-circuit detection is switch on or off
with a jumper inside the module. If a sensor track fails to work
properly due to contamination or corrosion, short circuit-detection
serves as backup. A reliable operation of the module is thus guaranteed
at all times as two separate switching relays are utilized.
The module will adjust to the correct polarization even
if a train bridges a disconnecting point when the system is switched
on. In this case the loop section of the layout will be powered up with a
slight delay relative to the main section.
With no sensor-tracks or track-contacts installed, the
module operates effectively, relying exclusively on short-circuit
The module may also be used in analog mode; however, a separate power supply is required for the loop section.
In analog mode, no train may bridge a disconnecting point when the system is switched on.
