ASi (Actuator-Sensor Interface) Valve Position

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
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 |
| 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 (ASi 3.0 Available on Request)
|
| 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. |
