ASi Valve Position Monitoring

ASi makes it simple.

Equipping Moniteur VPTs with an ASi interface card adapts your on/off automated valves to an advanced ASi valve network.

Money and time are saved as installation and maintenance are streamlined with reduced wiring and improved system diagnostics.

The ASi network protocol was developed to provide industry with a simple and cost effective method of networking on/off sensors and devices.

An ASi network can interface directly with your plant’s PLCs or through other protocols such as DeviceNet, Foundation Fieldbus, Modbus or Profibus with a gateway.

Moniteur’s Advanced ASi Platform Improves Reliability

The Network Card

A full function encapsulated network card for the ASi protocol – now to ASi v2.1 – 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
  • A Separate addressing plug is located on board, allowing “in the field” addressing with an ASi hand-held programmer.
  • 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.

ASi 2.1 Protocol Features and Specs

  • Supports up to 62 nodes or addresses (1-31 A + B)
  • Baud rate at 167Kbit (No termination required)
  • Scan time < 10ms for a fully loaded system Deterministic – each slave adds 150 µs to the scan time
  • Can be installed in any topology Bus power and communications share the same 2 wire cable
  • Standard 16AWG or special AS-interface flat cable can be used 990 ft. total bus length (with maximum 2 repeaters)
  • High level of noise and temperature immunity make ASi an excellent choice for the process plant environment.
  • Each AS-interface node requires its own unique address (master/slave)
  • No configuration software required
  • Nodes can be addressed using buttons on master, hand-held programmer, or through serial communications

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 only 2 or 4 wires eliminates wiring “spaghetti” of older schemes.
