This is the number of safety input points on the Unit.
This is the number of test output points on the Unit. The test output points are used with the safety
input terminals.
This is the polarity that the Unit uses to connect to input devices. There are
models with NPN and PNP connections.
This is the rated input voltage of the Unit.
This tells whether the Unit supports the connection of OMRON Special Safety Input Devices (D40A
Non-contact Door Switches, E3FS Single Beam Safety Sensors, etc.).
In the following table, the following abbreviations are used.
Yes: Can be connected
No: Cannot be connected
This is the number of safety slave connections that the Unit can have through Safety over Ether-
CAT (FSoE). You can connect to one Safety CPU Unit for each safety slave connection.
The I/O refreshing methods that are used by the Unit.
Only Free-Run refreshing is available.
In the following table, the following abbreviation is used.
Free: Free-Run refreshing
