The MSIsafesoft configuration software specifies the clock signals to be used as follows:
–
For the "even" inputs (IO0 and IO2 as well as I4 … I10), cross-circuit detection is realized
with the test pulse on TM0.
–
For the "odd" inputs (IO1 and IO3 as well as I5 … I11), cross-circuit detection is realized
with the test pulse on TM1.

Supply connections
Yellow
MSI-TBUS
The logic of the MSI-EM200-8I4IO safe extension module is supplied with voltage via the yel-
low MSI-TBUS DIN rail connector.
A1/A2
Supply connection A1/A2 is used to supply the configurable inputs/outputs as well as the con-
figurable clock/signal outputs with voltage.
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.
WARNING: Loss of the safety function through interference
EMC interference can lead to the loss of the safety function.
•
Connect the output-side GND connection of the power supply unit to the functional earth
(FE) of the system.
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.
