Mounting and removing modules
Tools
Order of the modules
Maximum number of modules
No tools are required for mounting the modules.
A standard tool, e.g., a bladed screwdriver with a blade width of 2.5 mm, is neces-
sary for removing the electronics modules and using the spring levers.
The modules on the DIN rail can be put in any order behind the bus coupler. To
ensure functionality, mount the modules side by side, without a gap.
If you are using modules with overall shielding braid, installing them next to each
other is recommended in order to make optimum use of the busbar for overall
shielding braid.
The maximum number of IndraControl S20 modules within a station is 63.
The actual number of modules within an IndraControl S20 station may be limited
by the supplied logic current, the current consumption of the connected modules,
and the system limits of the bus coupler.
The bus coupler, controller or the power module for the communications power
provide the power supply for the local bus. In the module-specific documentation,
this current value is specified as "Power supply at U
The total current consumption of all IndraControl S20 modules arranged in the sta-
tion must not exceed this maximum current. The logic current consumption values
are specified for each module in the module-specific data sheet as "Current con-
sumption from U
".
BUS
The current supplied by the bus coupler, controller or the power module and the
maximum current that can be taken up by the connected modules, are noted in the
device description files (e.g., gsdml file). You can use these maximum currents in
the engineering tool for configuration in order to prevent an overload of the com-
munications power.
NOTICE
Observe the current consumption of each device when configuring an
IndraControl S20 station. It is specified in every module-specific data sheet and
may vary. As such, the permissible number of devices that can be connected
therefore depends on the station structure.
Install a power module for the communications power or create an additional sta-
tion if the maximum current consumption at U
DOK-CONTRL-S20*SYS*INS-AP02-EN-P
