Key Features
The Model 7751, 7752, and 7753 Source/Switch Modules are designed exclusively for use in the Model 2790 SourceMeter Switch System for electrical checks of airbag inflators and a variety of other automotive electrical test applications. These modules provide the programmable high voltage and low current sourcing, plus the multichannel switching support required to measure insulation resistance and conductor continuity in these applications.
The Model 7751 and 7753 modules include programmable DC voltage (50-500V) and current (0-50mA) sources, as well as relay switching. A built-in current-to-voltage converter on these modules is used with the voltage source to measure the insulation resistance. They can also be used to measure currents from 0-50µA. The constant current source is useful for measuring the resistance of bridgewires and shunt bars. Four banks of twopole relays provide a sufficient number of terminals to connect two single inflator units or one dual inflator unit to the Model 2790 mainframe for testing. The mainframe will accommodate two plug-in modules, so a single Model 2790 system can be connected to two test stands and be used to test two dual inflator airbag modules. Parallel testing in the form of "voltage soak with one card, measure with the other" is possible for both single and double test stand configurations. The switch matrix of the Model 7751 and 7753 simplifies implementing contact verification tests and allows the Model 2790 to verify test voltages and currents for increased measurement reliability.
