Inverting the Digital Input Signal
The active signal level depends on which potential the common inputs CMA and CMB
(terminals 11 and 17) are connected to. The alternatives are either +24V or ground (0V). See
Figure 4-6.
The 24V control voltage and the ground for the digital inputs and the common inputs (CMA,
CMB) can be sourced from either the internal 24V supply or an external supply.
Figure 4-6: Positive/Negative Logic

Positive logic (+24V is the active signal) = the input is active when the switch is closed.

Negative logic (0V is the active signal) = the input is active when the switch is closed.
