Profibus DP Position Monitoring

Products

Main Product Info
Manufacturer: Moniteur Devices 
Description:
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 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.
