3.1 Description
Input/Output-expansion module MSI-EM-IO84
3.1.1
The module MSI-EM-IO84 is an expansion module within the
system MSI 400 and it provides eight safe inputs and four safe
outputs. Features of the MSI-EM-IO84 are:
 Monitoring of safety switches and sensors.
 Transmission of data to the controller module MSI 4xx
 Receiving of data from the controller module and switching of
the outputs
 Fast Shut Off (direct switching of the outputs without data
transmission)
The module MSI-EM-IO84 does not operate independently. It
operates only in combination with a controller module MSI 4xx,
see the configurations-software MSI.designer.
The simultaneous use of several modules MSI-EM-IO84 and/or
MSI-EM-I8 is possible (up to twelve modules MSI-EM-IO84 and/or
MSI-EM-I8 overall in the system).
To supply the safe outputs, each input/output-expansion module
must be connected to an external voltage supply.
The module MSI-EM-IO84 provides two test signals for a cross
monitoring on the inputs. One test signal is provided on the test-
output X1, the other test signal is provided on the test-output X2.
Short circuit detection
MSI-EM-IO84 detects short circuits between the
two test-outputs (X1, X2), if the duration of the test
pulses is < 4 ms.
WARNING
If the duration of the test pulses is ≥ 4 ms, short
circuits between the test-outputs may remain
undetected

The module MSI-EM-IO84 is an expansion module within the
system MSI 400 and it provides eight safe inputs and four safe
outputs. Features of the MSI-EM-IO84 are:
 Monitoring of safety switches and sensors.
 Transmission of data to the controller module MSI 4xx
The module MSI-EM-IO84 can not operate independently. It

see the configurations-software MSI.designer.
The simultaneous use of several modules MSI-EM-I8 is possible
(up to twelve modules MSI-EM-IO84 and/or MSI-EM-I8 overall in
the system).
Voltage is supplied via the internal safety bus.
The module MSI-EM-I8 provides two test signals for a cross
monitoring on the inputs. One test signal is provided on the test-
outputs X1, X3, X5 and X7, the other test signal is provided on the
test-outputs X2, X4, X6 and X8.
Short circuit detection
MSI-EM-I8 detects short circuits between the two
groups of test-outputs (X1, X3, X5, X7) and (X2,
X4, X6, X8), if the duration of the test pulses is
WARNING
< 4 ms.
If the duration of the test pulses is ≥ 4 ms, short
circuits between the two groups of test-outputs may
remain undetected.
Short-circuits inside of a group of test-outputs
(X1, X3, X5, X7) or (X2, X4, X6, X8) will not be
detected.
 This has to be observed during the wiring of the
safety switches or sensors, e.g. by a separate
laying or by shielding the wires.
