3.2 Electrical Safety
•
Operate the module only with low voltage according to the speci ications in the technical
data chapter. Only use power supplies, such as trans ormers or digital control stations, that
are certi ied or use in model railway applications. Connection o higher voltages (e.g. 230 V
mains voltage) is not permitted, also not on relay contacts. There is danger to li e through
an electric shock and a risk o ire!
•
Adhere to the limits on maximum allowable current according to the speci ications in the
technical data chapter. Exceeding the limits leads to overload and destruction o the device
and bears the risk o ire or electric shock.
•
Switch o the power supply be ore working on the electrical connections.
•
Pay attention to appropriate wire cross sections (rule o thumb: 0,1 mm² per 1 A maximum
possible current, e. g. 0,5 mm² cross section or 5 A maximum current).
3.3 eat Generation
Electronic components on the product may heat up during operation.
•
When mounting the product, ensure su icient air circulation around the device to prevent
heat build-up and overheating. This especially applies when installing the board in a hous-
ing.
4 Function of the bogobit Bremsmodul
4.1 General Function
The Bogobit Bremsmodul Classic is a brake module or digitally controlled model railways. The
module generates a “brake voltage”. This brake voltage, when applied to the track, lets locos brake
smoothly i they are equipped with a suitable decoder. It can be used on model layouts with center
stud tracks (Märklin H0). It can be used on digitally controlled model railways using the Märklin/
Motorola/m x protocol.
The brake voltage is basically just negative DC voltage. This working principle is known to märklin
users as the “märklin brake module”. Locos with digital decoders or the Märklin/Motorola/m x
protocol brake, i the voltage on the center studs is not the digital voltage, but a dc voltage. The
polarity o the center studs is negative with respect to the rails. Some old or simple decoders, such
as Delta and 6080 decoders, may stop in the brake section abruptly, but the vast majority o mod-
ern decoders brake smoothly.
Thus, to brake a digital controlled loco smoothly, an isolated track section is required, whose cen-
ter studs are either connected to digital voltage (the “proceed” state), or to dc voltage (the “brake”
state). However, i dc voltage is applied, and a loco travels over the track isolation, the pickup shoe
will cause a short circuit between the digital voltage outside, and the dc voltage inside the brake
section. Such a short is avoided by additional track sections, a so-called transition track section be-
