The MSI 100 and MSI 200 safety modules are, with respect to their functionality and basic
design, largely identical.
Both of the safety modules are described together in this chapter.
Also note the additional information provided for the MSI 200 and the safe extension mod-
ules.
The difference between the two safety modules lies in the following properties:
– MSIsafesoft diagnosis
– Connection option for safe extension modules of the MSI 100/200 system

Product description

Observe the technical data for the safety modules. 
See "Technical data and ordering data" on page 101.
MSI 100 and MSI 200 are configurable safety modules with 20 safe digital inputs. The inputs
are used to connect safe sensors or command devices. The maximum number of sen-
sors/command devices is dependent on the wiring:
– Single-channel wiring: maximum 20 safe sensors/command devices
– Two-channel wiring: maximum 10 safe sensors/command devices
The safety modules have four safe digital outputs. The outputs are actuated after evaluating
the incoming signals according to the configuration.
The safety modules have two ground-switching outputs. The ground-switching outputs are
used, for example, to switch off a contactor that is connected to the safety module. The con-
tactor can be switched off here via either the safe 24 V output or via ground. Use of the ground-
switching outputs increases the shutdown protection and cross-circuit protection of the safety
circuit.
The safety modules have four non-safe digital signal outputs. The signal outputs are used to
control, e.g., a non-safe PLC or signal units.
The safety modules have two clock outputs. The asynchronous test pulses enable safe cross-
circuit detection at the inputs of the safety modules that is dependent on the configuration.
The safety modules are available with either screw connections or with spring-cage connec-
tions. All connection terminals are pluggable. The individual terminal blocks are mechanically
coded to prevent swapping or skewed plug in.
