Introduction 30
Model 497.01 Analog Chassis
The plug-in modules installed in the 497.01 Analog Chassis provide four main
functions:
• Interlock control—An interlock control plug-in module provides
programmable interlock signal mapping between the test processor and the
modules installed in this analog chassis.
• Processor/Analog Chassis communications—A communications module
provides data conversion between the test processor and the 497 analog
plug-in modules.
• Transducer conditioning—AC and DC conditioners provide transducer
excitation and output signal amplification for both low-level and high-level
transducers.
• Valve drive signals—Valve drivers provide drive current for two- and three-
stage servovalves according to command inputs received for each channel.
Analog Chassis (Front Panel)
This chassis shows the maximum complement of modules for a standard
FTIIm system. Customized systems can use all the module locations.
Note
This chassis has rear panel transition modules and I/O connectors
to support up to four independent test stations.
