Bus X
The racks, distributed on bus X, are connected to each other by bus X extension
cables whose total length is 100 m max. Using
TSX REY 200
bus X remote modules
enables the length of bus X to be increased to a maximum of 2 x 350 m (see page
2/12).
The racks are connected to each other by means of bus X extension cables

bus X extension cables are supplied with 2 adaptors to be
fitted at each end and which provide greater protection against any strong electrical
transients that may occur between the racks (according to standard IEC 61131-2).
Line terminators
The two extendable racks located at the ends of the line must have a line terminator

racks are the basic elements of Premium multirack configurations.
They provide the following functions:
b
Mechanical function: they enable all the modules of a PLC station (power supply,
processor, discrete I/O, analogue I/O, application-specific modules) to be fitted
b
Electrical function: they allow connection and continuity of the the bus X and
provide distribution of:
v
power supplies required for each module in the same rack
v
data and service signals for the entire PLC station where this station has several
racks.
To meet user requirements, several types of rack are available (4, 6, 8 or 12
positions) in order to make up PLC configurations comprising up to 16 racks max.
distributed on bus X.

fan modules installed above the racks of Premium PLCs provide
forced air convection, in order to maintain an even ambient temperature inside the
enclosure and to eliminate any hot spots that may exist (see page 2/2).
