LNK-AI Analog Input Peripheral Device

    Key Features

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