Datasheet Items for Safety Input Unit
The following table gives the meaning of the datasheet items for the Safety Input Units.
Item Specification
Number of safety input points This is the number of safety input points on the Unit.
Number of test output points This is the number of test output points on the Unit. The test output points
are used with the safety input terminals.
Internal I/O common This is the polarity that the Unit uses to connect to input devices.
Rated input voltage This is the rated input voltage of the Unit.
OMRON Special Safety Input De-
vices 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.).
Number of safety slave connec-
tions This is the number of slave connections that the Unit can have through
FSoE. You can perform communications with one FSoE master device per
connection.
I/O refreshing method This is the I/O refreshing method for the Unit.
