Description
9905-969 is a Linknet 6 Channel Analog Input Module manufactured and designed by Woodward.The NetCon control system can use low-cost, simple-to- implement distributed I/O capabilities thanks to the LINKnet distributed I/O network. LINKnet I/O modules are ideally suited for non-turbine control tasks like sequencing and monitoring even though they are slower and less potent than NetCon I/O modules.
Applications
Petrochemical Plants: Uses high isolation to safely process transmitter signals in refinery areas.
Thermal Power Plants: Uses onboard display and keypad for quick calibration of turbine loops.
Water Treatment Plants: Operates in high humidity while monitoring flow and level via networks.
Natural Gas Plants: Performs reliably in outdoor control cabinets across wide temperature ranges.
Metallurgy Plants: Protects control systems from high-voltage electrical interference.
Network architecture
One NetCon module powers four independent network trunks, supporting up to 60 I/O modules per trunk. Each LINKnet module connects to the NetCon controller through a single twisted-pair wire, allowing one controller to manage up to 240 LINKnet modules.
The NetCon controller features four channels, each operating in a separate rate group defined by the MOE coder program. All nodes within the same network run at the same speed.
Each LINKnet module uses two rotary switches for network address setup. The switch setting must match the module number (1–60) configured in the MOE coder.
Hardware
There is a single, plug-in NetCon module and numerous I/O modules in every network. Thermocouple, RTD, discrete, (4 to 20 mA), and other I/O modules are included, as are relay output and (4 to 20 mA) I/O modules. Six channels are present on each of the analog modules. Eight channels make up the relay output module, whereas 16 channels make up the discrete input module.
