Mitsubishi Electric Corporation A1SX10 Input Unit Module

The Mitsubishi Electric Corporation A1SX10 Input Unit Module provides 16 input points with a common terminal, designed for 100–120 VAC operation and a 6 mA current draw. This module functions as an input interface within Mitsubishi Melsec automation systems, allowing multiple field signals to be connected to a single module for processing by the controller. The 16-point configuration with a shared common terminal simplifies wiring and reduces panel space when expanding input capacity in compact or distributed control applications. By clearly stating its supply range and current requirements, the A1SX10 supports predictable performance in environments where AC signaling is used, and it helps organize input wiring with consistent termination references. This model offers a straightforward path to scale input channels without adding unnecessary complexity to the control architecture.
