WOODWARD 9905-970 LINKNET 6 CHANNEL Analog Input 100 Ohm RTD
Description:
The LINKnet* distributed I/O network provides low cost, easy to implement distributed I/O capabilities for the NetCon* control system. The LINKnet I/O modules, while slower and less powerful than NetCon I/O modules, are well suited for non-turbine control functions like sequencing and monitoring. The network consists of a single NetCon module which provides four independentnetwork trunks of up to 60 VO modules each. The LINKnet modules, or nodes, oneach trunk are all attached to the NetCon controller module via a single twisted paiwire. One NetCon controller module can, therefore, interface with as many as 240LINKnet modules, each having multiple l/O channels, through four twisted pair wires.Each of the four channels on the NetCon controller module may run in a differentrate group. The rate group for each channel will be defined in the MOE* coderapplication. All nodes on a network will run at the same rateEach LINKnet module has two rotary switches that are used to set the networkaddress. On installation, these switches must be dialed so that the module's number1 to 60) matches the network address defined for this node in the MOE coder.
Each network consists of one standard, plug-in NetCon module and many I/O modules. The I/O modules include thermocouple, RTD, (4 to 20) mA, and discrete input modules, as well as (4 to 20) mA and relay output modules. All of the analog modules consist of six channels per module. The relay output module contains eight channels, and the discrete input module has 16 channels.
Each I/O module is housed in a plastic, Phoenix field termination module type package for DIN rail mounting. The modules can be mounted in the control cabinet or in any convenient location in the vicinity of the turbine that meets the temperature and vibration specifications.
A LINKnet Termination Module must be installed as the last LINKnet module on the networ
