Siemens 3SU1400-1GD10-1AA0 IO-Link Interface Module

Siemens 3SU1400-1GD10-1AA0 IO-Link interface module for ID key-operated switches integrates five programmable electronic switches, a built-in controller, and RFID authentication of the switching function into a compact IO-Link device. Finished in black and designed for front-panel mounting, it operates from 24 V DC and uses screw-terminal connections for reliable field wiring in industrial control cabinets and machines. As an IO-Link device, it interfaces with an IO-Link master to translate operator actions on the keyed switch into digital inputs for the control system, enabling secure access control and local switching functions with minimal cabling. This module provides a secure, panel-mounted solution for industrial environments that require RFID-based authentication and multi-switch control directly from an IO-Link network.
