The ME...TBUS modular electronic housings have
been designed especially for bus applications in which
it is frequently necessary to disconnect entire individual
modules from the whole.
Mounting rail bus connectors ME 17,5 or ME 22,5
TBUS 1,5/5-ST-3,81 are positioned in the DIN rail and
snapped together to contact the communication and
power signals in parallel with one another. The
ME...TBUS modular electronic housings with widths of
17.5, 22.5, 35 and 45 mm can be combined with these
bus connectors. The housing is mounted on the rail by
swinging it in in the familiar manner and is mechanically
guided by the DIN rail connector.
This concept allows entire individual devices to be
removed from the whole without interrupting the signal
chain.
The DIN rail bus connector is designed as 5-pos.
with a 3.81 mm pitch. Gold-plated contacts guarantee
high reliability of transmission. An extensive MINI
COMBICON range and matching cable housings are
available for supplying the signals.
Owing to the position of the plug deep inside the DIN
rail, more assembly space is available on the printed
circuit board with the same external dimensions for the
ME housing.
Versions with integrated function earth contact can
be supplied to improve electromagnetic compatibility.
To guarantee optimum heat regulation, there are
both open and closed housing versions. Flexible wiring
options with p.c. terminal blocks or plug connection
systems, with either spring cage or screw connection
systems round off the range.

Example:Power loss at 40 °C in ME 35
with vents, mounted in rows with spacing.
Pv40 °C = Pv20 °C x KI = 16.3 W x 0.81 = 13.20 W
As the maximum permissible power loss decreases with an increase in
the ambient temperature, the listed reduction factor (K1) must be taken
into account when calculating the permissible power loss.

The given power loss variables are dependent to a large extent
on
• the arrangement of the printed circuit boards in the housing
• the position ot the components (as a source of warmth)
• the number of equipped printed circuit terminal blocks in the housing.
• the housing installation position:

COMBICON plug connectors may only be actuated in the no-load
condition. If smaller loads need to be switched for operational
reasons, experimental values are available on request. (See also
COMBICON and P.C. Terminal Blocks).
At least one COMBICON pin strip or one p.c. terminal block per side
must be mounted on the p.c.b.
