Yes it has voltage adjuster.
Limits are 24V ± 8% ≈ (22 V – 26 V)

Yes it has both, voltage and current output protection.
Current limit is 116% of rated current ≈ 2.9 A
Voltage limit is 150% of rated voltage ≈ 36 V

It has two discrete outputs, DO1A and DO1C, with a shared common output, DO1B).
DO1A is normally open, meaning it remains open under normal operating conditions and closes when protection is tripped. Conversely, DO1C is normally closed, meaning it...

Parallel and serial connection of multiple PASFs is possible
Scheme of connection is :
