MELSEC ST is Mitsubishi's highly flexible remote I/O series which can be connected to either CC-Link or Profibus based networks using optional head stations. ST stands for Slicetype Terminal - the series is a complete remote I/O system using plug-in electronics modules.
Its modular architecture makes MELSEC ST exceptionally flexible, so that it can be configured precisely for any application. In addition to this hot swapping technology, gold-plated contacts, coded modules that prevent insertion errors and a high-speed backplane bus all help to make the system extremely reliable and user-friendly.
The MELSEC ST series is a universal solution for distributed automation systems.
Highlights:
Innovative and versatile modular design
Permanent wiring
Module replacement during operation at the touch of a button
Gold-plated contacts for permanently reliable connections
Error-proof module coding
