10. 2.3 Extension module for MS2/MT2 safety modules with OSSD safety outputs
A
If the MS1E41-024 is used as extension unit for MT/MS safety module series, both devices have to be supplied with
24Vdc. The OSSD safety outputs of the MT/MS have to be connected to the S12 and S22 input; the choice of
the OSSD outputs O1, O2, O3 or O4 is depending on MT/MS type and conguration respectively.
B
• Connection of OSSD 1 of the MT or MS master module on S12 for input 1
• Connection of OSSD 2 of the MT or MS master module on S22 for input 2
When both OSSD safety outputs of the master module are activated (high level), the safety outputs of MS1E41-024
switch ON, while the NC feedback output opens.
C
The OFF state of at least one OSSD safety 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.
D The NO safety outputs of MS1E41-024 will switch ON again if both input 1 and input 2 are activated.
