LNK-AI Analog Input Peripheral Device
Adds 4 additional analog inputs to a gas detection system. 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 one of the FCS Multi Channel System Controllers.
- Four 4-20 mA input channels
- Power LED indicator
- Modbus® RS-485 RTU communication
- Scaling and zoning capabilities supported by the controller
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 one of the FCS Multi Channel System Controllers.
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.
