AIMS Strain Gage and DC Amplifier Module This documentation describes the features, installation, and operation of the AIM8 Strain Gage/DC Amplifier Module for the Series 500 and System 570. This manual also contains specific progra mming information which is essential to understanding and us- ing the AIM8 module. This manual is not a general-purpose source on strain gages or DC measurement techniques. The user must select strain gage transducers and bridge configurations ac- cording to the application. For specific applications information on strain gages, consult the literature produced by strain gage manufacturers. The AIM8 is a highly versatile module used to measure strain-related parameters. It is compatible with a wide variety of resistive and semiconductor strain gage transducers. The AIM8 includes several advanced features which contribute to its performance, ac- curacy, and overall flexibility. Four channels: The AIM8 has four channels. Each can support a full, half, or quarter strain gage bridge. The AIM8 supports the use of quarter bridges with or without lead compensation. High-gain, low-noise amplifier: The AIM8 offers software-programmable local gains of 1, lo, 100, or 1000. Local gain can be combined with global gain for total gain of up to lO,OOO. Maximum noise is 2V peak-to-peak to lOI&, and 4pV p-p from 1OHz to lkH.2. High sensitivity: The AIM8 provides usable measurement sensitivity in the microvolt region. Extensive transducer compatibility: The AIM8 accepts resistive and semiconductor strain gages with values from 1203 to several thousand ohms. On-board bridge completion facilities: The AIM8 includes spring-loaded pin sockets for quick installation of jumpers and bridge completion resistors directly on the module. Adjustable excitation: The AIM8 provides regulated, independently-adjustable excita- tion of OWOV at up to lOOmA for each of its four channels. Internal or external excitation: Power for the on-board excitation sources is derived from the data acquisition system +l5V supply. The AIM8 contains on-board ter- minaIs for connection of an external excitation power supply if necessary. Document Number: 501-901-01Rev. C AIM84 Excitation voltage readable via software: Internal AIM8 channels 4, 5, 6, and 7 read the excitation voltage of channels 0, 1, 2, and 3, respectively. Quick-disconnect terminals: The AIM8 includes quick-disconnect' terminal blocks for easy connection to strain gages and an external excita
