Anyone aware of childrens building systems by them. (Modern version of Meccano
- but much better).
I'm interested if anyone knows anything about a relay: em10 with details in
Or any suggestion for a better group or other forum to ask in?
PS Not talking about plugs for walls ;-)
I hope their products are better than their webpages. Almost all the
links seem to result in "404 - Page not found". Try the links here, for

Relay module RB Ij
Unlike the electronic relay module RB I in the ec 1 and hobby 4 modular
system, this module contains no amplifier. The RB II is in addition to
the additional pack em10 in ec3-, hobby3-, ut3- u. ut4 kit included.
The relay module RB II contains a DC flat relay with two changeover
contacts. As the diagram shows, in idle state ai is connected to a2 and
bi to b2. Attention! The RB II can not be directly controlled by the
outputs of the fischertechnik electronic components (basic module,
flip-flop, mono-flop, AND-NAND, OR-NOR, dyn. AND). To control a relay
with these components, the RB I with built-in amplifier should be used.
The relay module can be connected to the other fischertechnik electronic
components by means of tongue and groove. The laterally arranged contact
strips are used for looping through "+" and in electronic circuits. In
each case, a red intermediate plug must be inserted between the housing
of the electronic components. There is no direct connection of the "+"
and contact strips to the terminals of the built-in relay.
If a motor does not run smoothly after switching off but is shut down
quickly, as is the case with safety circuits, for example. B. is
required, so the motor must be additionally shorted when switching off.
The dotted line causes this shorting of the motor.
A frequently required type of circuit is the pole reversal circuit.
If the 2 changeover contact sets are connected by 2 connections
according to the following diagram, the electr. Consumer, in this case
the fischer technology engine, in each case reversed polarity.

Excellent - many thanks.
Could you say exactly what you used to get that please?
I was interested in the use of the contact strips - there are 2 strips of metal
about 3mm wide down each of the four sides of the unit.
Must admit - I'm not much the wiser about them - I think that you can attach
other units to the relay box - and then electrically connect them in some way -
I am unsure why.
I went to the URL someone posted:
Right clicked a PDF and saved it to a file. Opened that in Abbyy Fine
Reader and OCRd it. Output that in plain text to the clipboard, then
went to translate.google.com and pasted it in. Posted the translation as
It looks like the box is designed to interlock with adjacent similar boxes:
I would guess there is no electrical connectivity other than via fly
I fed the URL straight into an online OCR page
and then copied and pasted the result of that into
It gave practically identical results (and OCR/translation errors) to
