Hello,
We have the following pressure sensor ( shown in attachment) which has a pnp output. Will this be able to to be wired to a DI card (6DL1131-6BL00-0PH1) in the following way

24V from control panel to pin 1
o v to pin 3
signal to digital input channel eg DI.2+ ( 3) on the card

or will this instrument require an interposing relay as it is a transistor output?

thank you

Me think that you should use 2wire type connection using terminal block of the type "potentiel distributor"..
Refer to page 13/14 of OEM manual
It is well described how to connecy/wire such sensor.
Glad to help you!
