Software Controlled Relay Outputs
Each IMx-S 16 has four and IMx-S 32 has eight software controlled relay driver outputs
labelled as Dig1 OUT through Dig4 OUT (see terminal list above). These relay driver
outputs can be connected to relays as shown in the figure below.

Note that terminals Dig +12V always have the voltage +12 V, whereas terminals Dig1
OUT to Dig4 OUT are low side drivers known as open collectors.
