Leuze electronic
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

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.
The logic of the MSI-EM200-8I4IO safe extension module is supplied with voltage via the yel-
low MSI-TBUS DIN rail connector.
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.
•
Supply connection A1/A2 is used to supply the configurable inputs/outputs as well as the con-
figurable clock/signal outputs with voltage.
