7751

The 7751 is a high voltage Source/Switch Module designed exclusively for use in the model 2790 source-meter switch system for electrical checks of airbag inflators and a variety of other automotive electrical test applications. This module provides the programmable high voltage and low current sourcing, plus the multi-channel switching support required to measure insulation resistance and conductor continuity in these applications. This module includes programmable DC voltage and current sources, as well as relay switching. A built-in current-to-voltage converter on this module is used with the voltage source to measure the insulation resistance. They can also be used to measure currents from 0 to 50µA. The constant current source is useful for measuring the resistance of bridge-wires and shunt bars. Four banks of two-pole 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.

• Sourcing and switching for airbag inflator testing
• Low energy sources, hardware source interlock/programmable shunt prevent accidental detonations
• Built-in I/V converter
• Programmable 50 to 500V voltage source
