Series 6100 Automated Amplifiers

Enclosure Details

Series 6100 and 6000 Enclosures are common between the 2 product lines and can accommodate any combination of Series 6100 I/O Modules. Enclosures are available in a variety of sizes and a selection of AC and DC powered versions to meet the needs of laboratory and portable field applications. With USB 2.0 and Ethernet interfaces available, facility integration couldn’t be easier.

Common Enclosure Features

  • Any number or combination of racks
  • Multiple, distributed system support
  • Supports any I/O module in any slot

 

The native interface for the enclosure is USB 2.0 and can be configured for Ethernet. There are many ways to configure a system. Multiple racks can be combined to provide a single larger system or used individually to create smaller, lower channel count installations. The systems can be run locally (near a test cell) or remotely from a control room. This allows the test operators to setup, configure and calibrate the system locally near the test article and remotely while a test is in progress.

An Operator’s Workstation is the primary control and data recording point for the Series 6000 System. Typically installed in the control room, the Operator’s Workstation runs PI610 Signal Conditioning Software for system setup, calibration, display, recording, distribution and export. Multiple, distributed systems are supported and controlled through a single Operator’s Workstation. A system can even be configured and used over wireless technology, allowing even greater control over the system. For example, a technician can change gain and filter settings on a touch screen tablet style PC while performing system checkouts and test readiness.

Description

Series 9300 are fully programmable, modular signal conditioning amplifiers for use with transducers and other low-level signal sources. An on-board microprocessor automates operation, reducing setup time and assuring high-quality measurement data. Programming and control are by IEEE-488 interface using a high-level programming language or Windows software. The optional control panel enables setting and display of operating parameters locally with display of excitation voltage and current and amplifier output.

The 9355 is a transducer amplifier with a guarded 2 to 10 wire input. It has bridge completion, programmable constant voltage and constant current excitation with remote sensing and excitation interrupt, automatic balance, shunt calibration, programmable gain instrumentation amplifier and programmable filter. DAC controlled shunt calibration with 4096 steps is standard and 4-step, bipolar double resistive shunt is optional.

Within the 9355, bridge completion and calibration components mount on a plug-in, front panel installed completion card that has a holder for channel identification data. Switches on the completion card set transducer specific operating parameters and identification. Completion cards are available for special requirements such as dynamic strain, 28 Volt excitation, voltage-mode charge, input attenuation and many other standard and customer-specific applications.

Gain is programmable from 1 to 10,000 with 0.05% resolution and 32 preset steps. Ten gain steps are factory calibrated providing ±0.1% accuracy. The remaining gain steps may be user calibrated or employed as variable gains for engineering units calibration. The amplifier operates from grounded or floating sources providing 120-dB rejection for common mode voltages to ±300 Volts.

Buffered Data and Tape outputs supply ±10 Volts full scale. Each output may be selected for wideband or filtered response. The standard filter is a four-pole, Bessel low-pass with eight programmable bandwidths and wideband. Output and excitation can be read over the computer interface and on the optional control panel. The control panel sets and displays excitation, gain and filter; controls balance, zero, calibration and input modes and displays the output and excitation voltage or current level.

Channels may be programmed individually or as a group using IEEE-488 or RS232. Adapters are available for Ethernet. Programmed operating parameters are kept in non-volatile memory and are automatically restored when the system is powered up or reset. PACWin93 control and display software is optionally available for operation under Windows 2000/XP. User programming is supported by a high-level instruction set and National Instruments LabView driver. PI660 software includes a feature for programming the 9355s when used as the front end for Pacific’s Series 6000 data acquisition system.

Ten channels, each with integral isolated power supply, mount in a 7-inch high rack enclosure. Multiple enclosures can accommodate up to 160 channels on each bus address. Interface adapters are available for Ethernet and USB 2.0.
