NetPod 4004

High Speed Synchronized Data Acquisition System
Data Acquisition Systems
Introduction

The NetPod 4004 is a new member of the high speed series of instruments that have been designed from the outset to offer everything needed in a stand-alone instrumentation for both local and distributed measurement solutions.

The 4004 provides high levels of data synchronisation both among channels within an instrument and instruments across a network.

                                     other ranges upon request.
Thermocouples           Types B,C,J,K,R,S,T
Thermistor                   Any standard device

Resistance                   Details on request

Analogue Output          +/- 30 mA / +/- 10V  
                                     Software Controlled

Strain Gauge                Full, ½ and ¼ bridges
                                     120,350,500 and 1 K Ohm Gauge

Each of the sensor inputs use a bayonet fitting plug and socket to attach signal inputs to the instrument. A physical release is needed to remove the sensor input from the device and so makes sure that the cabling remains reliably attached no matter the industrial environment in to which the instrument is deployed.

Software Support

The NetPod 4004 is supported by drivers for most modern data acquisition and SCADA software such as:

National Instruments Labview
DasyLab   
SCADA ... Spreadsheets
Software Developers KIt -
Windows & Unix / Linux Operating Systems

Multi-user operating environment on request

Network Data Synchronisation

The NetPod 4000 series instruments support network synchronised data acquisition operations in that all channels, for all instruments on a network. The synchronisation ensures that all the individual analogue converters for each input channel on all instruments operate at the same sample rate and take their readings at the same instance in time.

The networked  synchronised readings are accurate to within a few microseconds.
4 x Analogue Input Card
Preset / Initialisation / Boot time Output

The NetPod 4004 analogue output ports initialise at the 0 level no matter if they are in current or voltage mode, for approximately 2 seconds after which they automatically adjust to their preset levels.

The digital output ports can be settle to there preset condition immediately after initialisation.

All output levels are set within the driver software.

Software Defined Processor

The NetPod 4004 uses the new high speed NP-SF4000-100T software defined processor card. This processor card offers high speed network operations and connects to an external network using its on-board 100 BaseT port.

Software defined processing enables customisation of the NP-SF4000-100T card to be easily carried to suit any industrial applications.  The programmable device used in this system can be obtained from several different manufacturers and so enables a long operating life for this system without fear of obsolescence or problems of supply.

Analogue Interface Cards

All the analogue input cards contain individual analogue to digital converters, opto-isolation and sensor excitation. An in-built flash memory device stores the manufacture and calibration information.

Cards can be removed and replaced within other instruments and all systems information updated efficiently. Part number and calibration records can be automatically maintained.
