OVERVIEW
The R60AD8-G is equipped with the SIL2 mode certified according to the safety requirements of IEC61508: 2010 SIL2 and
IEC61511: 2015 SIL2. This mode is used when a customer builds a SIL2 system using products compliant with IEC61508:
2010 SIL2 or IEC61511: 2015 SIL2.
The R60AD8-G in SIL2 mode can be used to build safety functions for general industry machinery.
Module set
To use the R60AD8-G in SIL2 mode, it is necessary to use the following four modules in combination: two R60AD8-G
modules (SIL2 mode), one R60DA8-G module (normal mode), and one RY40PT5B module (normal mode). In addition,
configure the settings of R60AD8-G modules using GX Works3 so that a module near the remote head module is handled as
Main and another as Sub.
In this manual, these four module structure is referred to as the module set. Also, a system using the module set is referred to
as a SIL2 analog input system.
(1) R60AD8-G set to SIL2 mode and Main
(2) R60AD8-G set to SIL2 mode and Sub
(3) R60DA8-G set to normal mode

(5) Module set
In addition, to use the R60AD8-G in SIL2 mode, a redundant system must be configured based on a redundant master station
or redundant line. The module set needs to be mounted with the remote head module.
