Isolated Signals
This output signal is a fully-isolated 5-24V compatible output capable of sourcing or sinking current.
This output is normally open and only conducts current when a PSO fire event occurs.
The PSO Isolated Outputs are overload protected and will turn off if the maximum output current is
exceeded.

TTL Signals
This output signal is a 5V TTL signal which is used to drive an opto coupler or general purpose TTL
input. This signal is active high and is driven to 5V when a PSO fire event occurs.
