My humble opinion
Use it if you need it
A load resistance may be required if the contact is solid state or has
an LED/Lamp across it=20
Even a small amount of leakage will prevent the input turning off
In the 8.1 doccumentation there is a small note in the 219 section
stating RL not needed for propper operation of the channel

Subject: [foxboro] FBM217 and TA P0916PS
Content-Type: text/plain;
charset=3Dus-ascii
Content-Transfer-Encoding: quoted-printable Those of you out there that
get involved with the field wiring of modules have you noticed the "RL"
circuit on the TA's for FBM217 and FBM219?
I can find no documentation on when you need to use an "RL" or what to
use. I have looked through B0400FA and the PSS for the FBM217. I also
called TAC and received no great enlightenment, just to look at the PSS.
The PSS's only enlightenment was in most cases no additional
conditioning was required.
Does anyone know where to find any kind of documentation on the subject?
