3.5 Advanced Safety Option Variants
3.5.1 General Information
Newer versions of the Advanced Safety Option have extended slot compatibility. The table Table 4 describes the supported slots for
different revisions of the option board. The compatibility is determined by the revision of the board 70CVB01938 (141X4588). See
Illustration 6 for the location of the revision information.

The Advanced safety option board contains a safe digital I/O for the control and status word signals.
The available connectors of the Advanced safety option board
4 two-terminal digital inputs
2 two-terminal digital outputs
2 STO outputs
+24 V supply
GND
It is possible to use the digital inputs for selecting ramps and for activating, acknowledging, and resetting safety functions. The two-
terminal digital outputs can be used as output signals of the SBC or the SSM function, or configured by combining various signals of
the option board.
If a connected device is powered by an external power supply, make sure that there is common ground between the device and the
Advanced safety option board.
N O T I C E
The digital outputs use internal diagnostic test pulses to make sure that the output logic operates correctly. These test pulses are
visible to external systems. See 11.2 Safe Input/Output Data.
3.5.2 Input Configuration
The 4 two-terminal digital inputs operate in a two-terminal equivalent mode: the state of both terminals must match each other
within a discrepancy time (see 11.2 Safe Input/Output Data).
