The GE-Emerson IC200MDL640 VersaMax Discrete Input Module includes inputs in each group that can be either positive logic inputs that receive current from input devices and return the current on the common, or negative logic inputs that receive current from the common and return current to the input device. Input devices are connected between the input terminals and common terminals.
Negative logic functionality requires module version IC200MDL650C / BXIOID3225C or higher.
Power for the module's operation comes from the backplane. Intelligent processing for the module is performed by the CPU or NIU.
