Signal outputs
M0 to M3
The non-safety-relevant signal outputs M0 to M3 are designed as digital semiconductor out-
puts.
The signal outputs are used to control, e.g., a non-safe PLC or signal units.
The signal outputs are linked in the connection editor of the MSIsafesoft configuration soft-
ware.
5.3.3
Supply connections
Yellow
MSI-TBUS
The logic of the MSI-EM200-4RO safe extension module is supplied with voltage via the yellow
MSI-TBUS DIN rail connector.
ATTENTION: Module defect
The signal outputs can be destroyed by incorrect wiring.
•
Do not connect the signal outputs in parallel.
•
Prevent feedback to the signal outputs.
Make certain that the GND potential of the signal receiver is the same as the GND potential
of the safety module.
You can find further information on linking the signal outputs in the connection editor in the
help system of the MSIsafesoft configuration software.
WARNING: Loss of the safety function
The use of unsuitable voltage supplies and the incorrect connection of the voltage supply
can result in the loss of the safety function.
•
Only supply the supply voltage at connections A1/A2 and 24/0V on the base device of
a MSI 100/200 system via the same voltage supply.
•
Likewise, supply the supply voltage for all other devices participating in the system via
the same voltage supply.
•
Only use power supply units with safe insulation and SELV/PELV in accordance with
EN 50178 / VDE 0160.
Connect the two supply connections (A1/A2 and MSI-TBUS) for an intended function of the
safe extension module.
ATTENTION: Module defect
The use of an incorrect DIN rail connector or of a terminating plug can result in a module
defect.
•
Only use the yellow MSI-TBUS DIN rail connector.
•
Never
use the green TBUS DIN rail connector.
