Pretty sure the pins on the IDC26 can be used as normal IO as is, just add them in hal as you need them.
Beware that those pins are very sensitive.
You can use "arduino relay boards" as most of those require inputs set to low to activate the realay and pins on the IDC are normaly high.
Do check the manual for this as i did not, i know all the Mesa boards i used have high pins on IDC.

Thank you!
I am aware of the "senitivity".
Can you give me an example for adding them to hal? I do not know the names of the needed ressources...

With LinuxCNC running:
halcmd show pin hm2 | grep gpio
Will list all the hardware gpio pins.
and:
halcmd show param hm2 | grep gpio
will list all hardware gpio parameters.
Note that all P1 I/O starts as an input an must be explicitly set to output
mode in hal, something like:
setp hm2_7i95.0.gpio.041.is_output true
halcmd show pin hm2 | grep gpio
Will list all the hardware gpio pins.
and:
halcmd show param hm2 | grep gpio
will list all hardware gpio parameters.
