Profibus DP Position Monitoring
|
|
|
|
Moniteur VPCs
with encapsulated Profibus
interface cards adapt your on/off automated valves to an advanced
Profibus DP valve network. The Profibus protocol was developed in
1989 by a group of factory automation suppliers.
Profibus-DP is a device level bus that supports
both analog and discrete signals. Profibus-DP has widespread usage
for such items as remote I/O systems, motor control centers, and
variable speed drives. Profibus-DP communicates at speeds from 9.6
Kbps to 12 Mbps over distances from 100 to 1,200 meters.

Moniteur's Advanced Profibus
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
each with an 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. |
