Two-way Track Module 2121, DC, analogue without case
Anyone who has built electronic modules for controlling starting and braking into their system before is familiar with a particular problem – while one train reaches its precise stopping point, a second stops hugely short of it and a third even continues at such a speed that it overshoots the mark entirely or halts abruptly! Regardless of what control attempts are made, nothing is 100% suitable for all vehicles! This is the result of the varying driving characteristics of each of the individual traction units. Therefore, we have developed a track module with speed-regulated delay. By measuring the approaching train, the slow speed during deceleration is set. In this way, faster trains are decelerated more, whereas slower trains are decelerated to a lesser extent, thus allowing each train to arrive at its intended target.
This microprocessor-controlled module functions using pulse width control. 64 speeds are available. The module can be used in both directions and is controlled by the polarity of the traction voltage and an individual control input for each direction dependent on the three integrated track occupancy indicators.
For use with station tracks that are used in both directions, block sections, single- and double-track in both directions. Aside from the occupancy indicator outlets for all three individual sections, there is also an overall occupancy indicator outlet for switching multiple track component 2021s in a row in automatic block section operation or for feedback via feedback modules 1051 and 1151.
Requires a traction current source (max. 12V=) and an adjunct current supply (16V~ or =) to operate.
Also available without casing at a lower price as 2121.

Universal Decoder 1131Universal Decoder 1131The Universal Decoder 1131 is freely programmable in terms of both its receiving address and its outlet switch time, and a special programming mode is incorporated in control centres with software version V2.12. and above for this purpose. The outlet switch times can be selected from 10 speeds from 0.2 seconds right through to continuous operation. Continuous operation is intended for use with the direct connection of light signals, thus four of the eight outlets are always active in this operating mode. The eight outlets are assigned to four pairs of address outlets. In continuous operation, the odd outlets are active (always the left-hand connector when connectors are lying upwards) in the home position (that is, after switching on the power supply) = stop (red).
The Switch-to-Ground Prinzip is to make it possible to use external power with higher voltage (up to 24V DC) for more powerfull switching and saving power from the trackswitch voltage source. 38,00 EUR (19 % VAT incl. excl. Shipping costs) |
