Logic modules The logic modules have eight integrated digital inputs, two of which can be configured as analog inputs (0–10 V). A further eight channels can be configured with corresponding relay or analog modules as digital inputs or outputs. The modules can be programmed with the intuitive LOGIC+ software.
