MSR330 Modules: Group 1, Group 2, Group 3
 
Functions: 
Safety contact outputs.
Outputs:
Each module: 3 x N/C outputs plus 1 x N/O safety contact outputs.
System maximum: 3 x 6 = 18 N/C plus 1 x 6 = 6 N/O auxiliary 
contacts. 
 
A minimum of one up to a maximum of six Output Modules can be included in a single 
MSR300 System. 
 
MSR330 Output Modules are available in three distinct versions, each specific for one of 
three output groups: i.e., Group 1, Group 2, Group 3 respectively. The group number 
must be specified when ordering these modules, and Output Group versions must 
correspond with the assignment settings of the Input Modules. 
 
The MSR330 is housed in a 22.5 mm wide DIN rail mounting enclosure with plug-in screw 
terminal blocks.
