7.3.2.1 Digital Input Signal Inversions
The active signal level is different when the common inputs CMA and CMB (terminals 11 and 17) are connected to +24 V or to ground
(0 V).
The 24 V control voltage and the ground for the digital inputs and the common inputs (CMA, CMB) can be internal or external.

A Positive logic (+24 V is the active signal) = the input is active
when the switch is closed.
B Negative logic (0 V is the active signal) = the input is active
when the switch is closed. Set the jumper X3 to the position
'CMA/CMB isolated from ground'.
