The Input channel LED will also remain OFF if the module isn't configured yet, or if it's configured incorrectly for the inputs.

Did you inadvertently associate either of the Test Output signal sources with the inputs ? The inputs would be expecting to see the pulse train from the Test Output, not a steady 24V signal (which would indicate a short to 24V).

Otherwise your wiring sounds correct for a light curtain or safety scanner connection, like the example on Page 62 of the POINT Guard I/O User Manual.

edit: answered correctly while I was looking at the user manual and contemplating coffee.
