Application and Wiring Examples for Safety Modules      Appendix C
Sourcing Mode
When the module is wired as shown, it is suitable for applications that are rated 
up to, and including, Category 2 as defined in ISO 13849-1. 
To achieve that suitability rating, you must perform diagnostic testing of the 
safety function. Configure the safety input channel for Safety Pulse Test to test 
the circuit for short circuits to 24V DC.

Channel Connections
This wiring example shows connections to Safety Output 0. 
You are not limited to using channel 0 in this mode. You 
can use all channels as determined by your application.
LA Power
The Local Actuator (LA+ and LA –) power connections are 
used to supply field-side power to the module.
• The 5069-OBV8S and 5069-OBV8SK modules do not 
draw current from the SA Power bus. The modules 
are DC type modules. Therefore, you must install them 
on an SA Power bus that uses DC power.
• If you install modules in a system that use AC SA power 
and DC SA power, you must install them on separate SA 
power buses.
• You use a 5069-FPD field potential distributor to 
establish a new SA Power bus in a system. SA Power 
buses are isolated from each other. To keep the modules 
on separate SA Power buses, complete the following 
steps.
1. Install the modules that use one type of SA power, for 
example DC, to the right of the adapter or controller, 
that is, the first SA Power bus.
2. Install the 5069-FPD field potential distributor to 
establish a second SA Power bus.
3. Install the modules that use the other type of SA 
power, for example AC, on the second SA Power bus.
•We strongly recommend that, if you have a direct 
connection between the safety output module and an 
input module and those modules are powered by 
separate power supplies, that you connect SA- and LA- 
together. This practice helps to eliminate grounding 
float from disrupting diagnostics.
