Remote I/O ST-Lite

MELSEC STlite - Optimized for real-life requirements
Approved for a very wide range of applications, the STlite series features excellent module granularity and fieldbus-agnostic design, making it ideally suited for the requirements of today’s distributed fieldbus systems. The devices are optimised for efficient process-level communication, with scalable performance and high integration density.

 

Highlights:

  • The range of potential applications is virtually unlimited
  • Reduces hardware and system overheads to a minimum
  • Simplifies handling and maximises efficiency

The uncompromisingly modular architecture of the system also extends to its support for a wide range of fieldbus systems. You can install different head stations for different protocols, depending on the needs of your applications.

  • Module granularity: 2, 4 or 8 channels in a single I/O module
  • Fieldbus-agnostic: Head stations available for the leading fieldbus protocols Profibus DP, CC-Link and Ethernet
  • Safe investment: Fieldbus node design enables easy switching to new bus standards without changing the busmodules
  • Clear labelling: Colour-coded group identification plate brackets and terminal tags
  • Versatile: Configuration options for digital/analog inputs/outputs and special functions with different voltages, powers and signals on a single fieldbus node

 

Reliable:

  • Approvals for industrial and marine automation applications ensure a wide range of deployment options – even in heavy-duty environments
  • Automatic contacting for power and data contacts
  • Pluggable connections with bus plug connector
  • CAGE CLAMP® spring terminals for input/output point connections

Marking:

  • Easily identifiable color coded WSB markers Inputs/Outputs
  • Status LED's for fast diagnosis

Internal Communication:

  • Safe automatic connection by gold plated self-cleaning contacts
  • gaslight, vibration proof and maintenance free

Pluggable connections:

  • CC Link STL-BT1
  • Ethernet Modbus STL-ETH1
  • Profibus STL-PB1
