PSO Interface [-EB1]

The Position Synchronized Output (PSO) signal is available on the -EB1 option board in two signal formats: TTL and Isolated.

The PSO signal is also available on the AUX I/O connector. Refer to Position Synchronized Output (PSO).

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.
