Safety Module Features Chapter 5
Safety Output
Module Features
This section describes features that are available only on the Compact 5000
I/O safety output modules, that is, the 5069-OBV8S and 5069-OBV8SK
modules.
The 5069-OBV8S and 5069-OBV8SK modules are safety output module that
uses eight safety outputs. You use the outputs in one of the following ways:
• Sourcing/sinking outputs in Bipolar Output mode
• Sourcing outputs in Sourcing Output mode.
The only difference between the 5069-OBV8S and 5069-OBV8SK modules is
that the 5069-OBV8SK module has conformal coating.
Safety Application Suitability Levels
Table 44 describes the safety application suitability levels for a 5069-OBV8S
module.
Table 44 - Safety Application Suitability for 5069-OBV8S 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.
• The module uses single-channel mode.
• Output Mode is Sourcing.
• Point Mode is Safety Pulse Test.
Consider the following:
• The channel mode type, that is, single or
dual, affects Category. You can use the
modules in SIL CL3, PLe 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.
• 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 I/O module resides 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.
• Output Mode is Bipolar.
Or
• The module uses single-channel mode.
• Output Mode is Sourcing.
• Point Mode is Safety Pulse Test.
• The channel is connected to an IEC 60947 certified actuator or contactor.
Additionally, you must use shredded cable or cable trunk to eliminate short
circuit faults on the channel.
Or
• The module uses dual-channel mode.
• Output Mode is Sourcing.
• Point Mode is Safety Pulse Test.
