Standard network systems for
monitoring and controls of automated

Intellis®
is a two-wire communications field network capableof
regulating the transmission of information from a
series of automated valve Network Monitors digitally
linked to one another.Network Monitors are standard
Westlock Control Monitorsexcept for the addition of
a serial communications network card.Each Network
Monitor houses two hermetically sealed positionsensors
for valve position monitoring, a low power solenoid
valvefor actuation control, and a network card communicating
via theModBus®, DeviceNet® or AS-interface®
protocol.
By
switching from a conventional hardwired I/O system to an Intellis®
network, immediate cost savings are realized through the elimination
ofhundreds of dedicated wires and their associatedcosts.
Network Card
Depending
upon the network standard selected (ModBus®, DeviceNet®,
AS-interface®), a dedicated network card is integrated
within the enclosure of each Network Monitor. The on-board
network card is available in two configurations. Network card
(A) is capable ofcommunicating and controlling two inputs
and one output. Network card (B) will communicate with and
control six inputs and two outputs.
