Yes, if the touch probe uses a contact to ground you can use a pull-up
resistor as Andy suggested.
For 7I76XX inputs this needs to be fairly stiff, say 2.2K 1/2W
This is because the 7I76XX input resistance is 11K and needs an input > 14.4V
for a high level at 24V Vfield, and a 10K resistor will not do this.
