Cisco 2X-DS3-STM Digital Input Module

Cisco 2X-DS3-STM Digital Input Module is a plug-in I/O component designed for Cisco control systems to read discrete input signals from field devices. It feeds digital status information into the controller’s I/O bus, allowing the PLC to detect states of sensors, switches, and other binary devices in real time. As part of the DS3-STM family, this module is intended for modular automation architectures where compact, reliable input channels are required in control panels, machine centers, and manufacturing lines. Typical applications include monitoring pushbuttons and limit switches on equipment, sensing proximity sensors for collision avoidance, and providing node inputs for safety interlocks or process sequencing. By consolidating multiple digital inputs into a single module, it helps streamline panel wiring and I/O budgeting within an Cisco ecosystem. This digital input interface is designed to integrate with compatible Rockwell Automation controllers and engineering software, supporting seamless configuration and straightforward diagnostics within standard PLC programming environments.
