DeviceNet Valve Position Monitoring
|
|
|
|
Moniteur VPCs with encapsulated DeviceNet
interface cards adapt your on/off automated valves to an advanced
DeviceNet valve network. Money and time will be saved as installation
and maintenance are streamlined with reduced wiring and improved system
diagnostics.
Based on the CAN protocol, the DeviceNet protocol
was developed by Allen Bradley to provide industry with a simple
and cost effective method of networking field devices. Moniteur
supplies a full range of accessories including cable and quick-
disconnect connectors to simplify installation.

Moniteur's Advanced DeviceNet
Platform Improves Reliability
|
|
The Network Card. A full function
encapsulated network card includes the following benefits:
|
| Encapsulated electronics
and position sensors ensure reliability in corrosive, humid
and dirty environments. |
Hall effect position sensors
designed for the card and provide optimum stability in
areas of high vibration. |
| Two transistor outputs
with a combined output of 4.8w @ 24VDC are available for
your solenoid valves and allow many standard DC NAMUR valves
to be used, avoiding special "low power" valves |
| High visibility LEDs are
located on-board for local indication of on -board sensors,
auxiliary inputs, outputs and network state. |
| Two additional inputs
are optional for local pressure or temperature switches. |
|
| The Enclosure Platform. Moniteur's
platform is available in a wide variety of enclosure materials to
match your hazardous or corrosive environment and is designed to provide
long-term reliability. |
| Housings in Aluminum or
SuperTough Zytel Thermoplastic for General Purpose
or Hazardous Areas |
| Moniteur’s patented
Loc-Ring Cam and Shaft Retention System ensures sensing
accuracy and a multi-million cycle life of the physical platform. |
| DIN 4-pin Female Micro
or 5-pin Mini plug connectors can be fitted to the conduit
entries of the enclosures to speed installation in general purpose
areas. |
| Moniteur's industry-preferred
indicator has a rated minimum life of 1,000,000 cycles.
With indicators still in service after 9 million cycles, you're
assured of long-term reliability. |

Additional Advantages
of In-Plant Networking
|
|
| Drastically Reduced Installation Costs
- Wiring and installation time are reduced, yielding a cost saving
up to 40% versus conventional methods. |
|
| Reduced Maintenance Costs and Increased
System Reliability - Components require less maintenance and are
designed to work "one way" only. Built-in diagnostic functions
allow components to be continuously monitored. |
|
| Faster Start-Up - Set-up is simpler
and diagnostic functions speed troubleshooting. |
|
| Simplified Plant Wiring - Automated
valves can be inter-connected in any configuration. Utilizing 4 wires
eliminates wiring "spaghetti" of older schemes. |
