Application and Wiring Examples for Safety Modules Appendix C
For Cat.4 applications, if your application remains in safe state, that is, the
output is off, for a prolonged duration, we recommend that you take one of the
following actions:
• Apply output monitoring at the actuator. The monitoring can be direct
or indirect.
• Limit the safe state to no more than 24 hours.
• Conduct functional test if safe state dwell time increases.

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.
