Two-way Track Module 2121, DC, analogue without case

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.

	Track Occupancy Indicator 2102 without case Track Occupancy Indicator 2102 without case This fourfold track occupancy indicator works via the current sensor principle and can be used for all types of current and control system, including digital DCC, Motorola, MFX, Selectrix etc. The function and occupancy status of the four track sections that can be monitored can be immediately monitored using the four integrated LEDs. All current consumers with a resistance of up to 15 kΩ can be safely detected. Digimoba signal box displays, our feedback modules 1051 and 1151 or LEDs with series resistors can be connected to the ports for external displays. Each of the four track occupied indicator outlets is capable of delivering up to 2A of switching current, thus making it suitable for use as a track switcher for direct switching. 31,20 EUR (19 % VAT incl. excl.
