Safety Module Features
This chapter describes features that are specific to Compact 5000â„¢ I/O
safety modules.
Safety Input
Module Features
This section describes features that are available on the Compact 5000 I/O
safety input module, that is, the 5069-IB8S and 5069-IB8SK modules.
The 5069-IB8S and 5069-IB8SK modules are 8-point safety sinking input
modules that use eight safety inputs and four test outputs. The 5069-IB8SK
module offers conformal coating.
Safety Application Suitability Levels
Table 42 describes the safety application suitability levels for a 5069-IB8S and
5069-IB8SK module.

Suitability Level Conditions Notes
Safety applications that are rated up
to, and including, SIL CL3, PLd,
Cat. 3 as defined in IEC 61508,
IEC 61511, IEC 62061, and ISO
13849-1.
(1)
• The module uses single-
channel mode.
• Point Mode is Safety Pulse Test.
Consider the following:
• The channel mode type, that is, single or dual, affects Performance Level and Category. You can
use the modules in SIL CL3 applications regardless of channel mode type.
The determining factor to whether a Compact 5000 I/O safety module resides in a SIL CL3, PLe,
Cat. 4 safety application is that the overall safety architecture be a dual-channel system.
• To achieve SIL CL3 single-channel, the sensor that is used must be SIL CL 3 single-channel
as well.
• The requirement that Point Mode be Safety Pulse Test assumes that only the safety modules
provide diagnostics to a specific Suitability Level.
The larger safety system within which the safety modules reside can provide the diagnostics
necessary to achieve the stated Suitability Level without the requirement that Point Mode be
Safety Pulse Test.
Safety applications that are rated up
to, and including, SIL CL3, PLe, Cat.
4 as defined in IEC 61508, IEC 61511,
IEC 62061, and ISO 13849-1.
• The module uses dual-channel
mode.
(2)
• Point Mode is Safety Pulse Test.
(1) Single channel could not be verified to PLe, Cat. 4 without a single channel sensor that is PLe, Cat. 4 rated.
(2) You do not configure the module to use dual-channel mode via the Logix Designer application module properties dialog box. You use a safety instruction to use the module in dual-channel mode.
