Allen-Bradley 1745-E103 is an expansion unit for the SLC 100 family of programmable controllers, designed to add discrete I/O capacity to an existing SLC 100 processor. It connects to the SLC 100 processor via a 1745-C2 ribbon cable and sits in the SLC 100 rack to extend I/O without replacing the central CPU. The module operates from a 120-240 VAC supply and has a maximum power requirement of 12 VA. Typical uses include adding extra I/O for small machine automation, process monitoring, or conveyor control within SLC 100-based systems.
