Overview

The PACSystems IC694MDL758 is a 12/24 Volt DC, Positive Logic Output module, providing 32 discrete outputs grouped into two isolated groups of 16 outputs each. Each group has its own dedicated common. These outputs are positive logic or sourcing-type outputs, meaning they switch loads on the positive side of the power supply and supply current to the load. The outputs can handle user loads in the voltage range of +12V to +24V DC (with a tolerance of +20% / -15%) and can source a maximum of 0.5 Amps per point.
