Safety Module Features Chapter 5
Use Test Output with a Safety Input
A test output can be used in combination with a safety input for short circuit
and cross-channel fault detection.
In this case, Point Mode must be Safety Pulse Test. Safety input pairs must be
associated with different Test Output sources.

TIP The test output can also be configured as a power supply to source 24V DC to
an external device, for example, a light curtain.

Channel Connections
The diagram shows devices that are connected to
safety input channels 0 and 3 and test output
channel 0 and 1. You are not restricted to using only
those channels.
You can connect devices to any safety input channel
or combination of channels as needed.
We recommend that you connect even-numbered
input points to even-numbered test output points
and odd-numbered input points to odd-numbered
test output points.
This wiring practice can maximize diagnostic
independence and separation.
SA Power
Connections to an external power supply that provides
SA power via the SA Power RTB on one of the following:
• Compact GuardLogix® 5380 Controller
• 5069-AENTR or 5069-AEN2TR EtherNet/IP™ Adapter
• 5069-FPD Field Potential Distributor
IMPORTANT: Remember the following:
• The 5069-IB8S and 5069-IB8SK modules use DC SA
power. You must connect DC power to the
component, that is, controller, adapter, or field
potential distributor, that provides SA Power to the
modules.
• 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.
