10.2 Application
10.2.1 Extension module in single channel mode
A
• Connection of NO safety output of the master module between S11-S12 for input 1
• Connection between S12-S22 for input 2
The safety relay output from a master safety module is activated and the safety outputs of MS1E41-024 switch ON,
while the NC feedback output opens.
B
The opening of the safety relay output of the master module forces immediately the safety outputs of MS1E41-024
to the open state, and the NC feedback output to the close state.
The MS1E41-024 is intended to expand the number of safety outputs of a master safety module. It must be wired correctly to a
master safety module to reach the needed safety category.
It can be used as an extension unit of safety modules with free-of-voltage relay output; it can also be used with the MT or
MS series safety modules with OSSD safety outputs, to provide for safety relay outputs.
