  • Arenas and Pools
  • and many more...

Key Features

  • Four 4-20 mA input channels
  • Power LED indicator
  • Modbus® RS-485 RTU communication
  • Scaling and zoning capabilities supported by the ontroller
  • Configurable default settings for any interruption in communication
  • Standard water / dust tight, corrosion resistant enclosure

Description

The LNK-AI Analog Input peripheral device adds four channels of 4 - 20 mA or 0 - 10 volt analog inputs to a Modbus® network configured with an FCS Flexible Control System Controller.
The LNK-AI is designed to receive an analog signal from one to four transmitters and communicates back to the FSC using Modbus® RS-485. The FCS monitors the connection and will indicate a loss of communications.

Ideal for large applications to create an efficient distribution network of specialized gas detection devices with fewer wires running directly from the controller.
