4 Function of the bogobit Bremsmodul
4.1 General Function
The Bogobit Bremsmodul Classic is a brake module for digitally controlled model railways The mo-
dule generates a “brake voltage” This brake voltage, when applied to the track, lets locos brake
smoothly if they are equipped with a suitable decoder It can be used on model layouts with center
stud tracks (Märklin H0), and for most applications also with two-rail tracks It can be used on digi-
tally controlled model railways using the Märklin/Motorola/mfx protocol and, depending on deco-
der characterstics, also with the DCC protocol
It is the characteristic feature of the Bremsmodul Classic that it only needs a single isolated track
section, i e a single isolated center stud section in the case of center stud track, or a single one-
sided track section in the case of two-rail track There is no technical need for transition sections or
stop sections This minimizes installation effort
The Bremsmodul Classic has two operational states: “proceed” and “brake” In the proceed state,
the unmodified digital voltage is applied to the track; in the brake state, a “brake voltage” is ap-
plied to the track instead The brake module has a control input to set either state The implement-
bogobit Bremsmodul Classic · 2016-08-01 page 3 / 12
ation of the control input varies between the different hardware versions of the Bremsmodul Clas-
sic
The brake voltage is basically just negative DC voltage This working principle is known to märklin
users as the “märklin brake module” and to DCC users as “brake on dc” It works with most of the
original märklin decoders and most compatible decoders It also works with many DCC decoders,
some of which need special configuration (CV programming) to support it
In some DCC decoders the voltage polarity is evaluated to achieve direction dependent braking
Thus, for two rail track applies: From the driver's perspective moving forward, the right rail of two
rail track is equivalent to the center studs of Märklin three-rail track
The brake voltage is output through an electronic current-limiting circuit Therefore, when driving
over a track isolation gap, no short circuit occurs and there is no disruption of service
4.2 ardware versions of the brake module
The Bogobit Bremsmodul Classic is available in different versions The differ in the electronic com-
ponents on the module, in their function, and in their connections The following version are avail-
able:
1 The version „Bistabil“ is the most common version Two input terminals, either of which
has to be activated for a short moment, allow to set the states “proceed” or “brake”, re-
spectively (this is like a turnout drive with double solenoid) For this purpose, the brake
module is equipped with a bistable (latching) relay
2 The version „Monostabil“ uses a monostable (ordinary non-latching) relay If a (permanent)
control voltage is applied to the input terminal, the the brake module is in state „proceed”
If no control voltage is applied, the brake module is in state “brake” (this is like a light on –
light off function)
3 The version „Bremsgenerator“ does not have a relay and no control input The brake mod-
ule is merely a brake voltage generator, permanently providing a negative DC brake voltage
The layout control electronics must provide a single pole double throw switch so that – de-
pending on the switch position – either ordinary digital voltage, or brake voltage from the
Bremsgenerator can be fed to the track

5 Connection and Operation
5.1 andling
The product consists of sensitive electronic components Improper handling may destroy them
Prior to handling the board, please discharge yourself from electrostatic charge To do this, touch a
metal object (earthed), e g a metal PC casing Try to touch the board only at the edges and avoid
touching any electronic components or copper routes on the board
5.2 Mounting
Mount the module properly, but not overly tight, to the model railway framework
If the module has an enclosure: Use the four holes at the corners (3 mm diameter) of the board for
mounting Use self tapping screws with pan head, head diameter 6 mm maximum Tighten the
screws carefully, so that the circuit board does not warp
If the module is a bare board without enclose: For mounting use the four outer holes at the cor-
ners These holes have 3 mm diameter Use self tapping screws with pan head, head diameter
6 mm maximum Use spacers (little plastic tubes) between circuit board and mounting surface
Tighten the screws carefully, so that the circuit board does not warp
Also consider the instructions related to heat generation in chapter 3 3

5.3.2 Notes on Wiring
For a layout with center stud track (Märklin H0) applies:
–
Create an isolated track section A center stud isolation must be inserted at both ends of the
track section
–
"B" has to be connected with the center studs ("B") of the regular track outside the isolated
section
–
"B#" has to be connected with the center studs of the isolated track section
–
"0" has to be connected with the rails ("0") Make this wiring just between the brake module
and the track
For a layout with two-rail track applies:
–
Create an isolated track section: On one rail (herein called the right rail) two cuts have to be
made to form an isolated section between The other rail (herein called the left rail) is not cut
but remains a continuous rail
–
"B" has to be connected with the right rail of the regular track outside the isolated section
–
"B#" has to be connected with the right rail inside the isolated track section
–
"0" has to be connected with the left, continuous rail
Generally applies:
–
∗The control inputs for the relay operation, RR, R and RG, have to be connected to a conven-
tional turnout control box (two momentary push switches) or to a digital turnout decoder The
polarity of the control voltage is irrelevant
–
∗if the voltage is applied to RR and R , the module goes to state “brake”
–
∗if the voltage is applied to RG and R , the module goes to state “proceed”
–
∗SR, S and SG are terminals of an unused single pole double throw relay contact It can be
used, e g , to operate a light signal, or to operate a stop track section
–
Only a single isolated track section is necessary No so-called transition sections or stop secti-
ons, as is customary with many other brake modules, are electrically required
However, a stop section might be reasonable for operational reasons, if it cannot be ensured
that any loco will come to a stop within the brake section Such a stop section is realised by
another track section that is wired via the terminals "S∗" and "SG" and connected with "B"

5.4 Connections – Version “Monostabil”
This section describes the version “Monostabil” of the Bogobit Bremsmodul
The version “Monostabil” uses a monostable (non-latching) relay
This version is suitable if a on-off-voltage is available This can be provided, e g , by the switch con-
tact built into the solenoid drive of a light or semaphore signal (originally intended to switch off
track voltage) It is also suitable, if a digital decoder provides a switchable voltage (e g as used to
switch the lights of a building)
