2790-A configuration (one 7753 module)
This test system includes a single 7753 module. This module has a programmable 50 to
500V V-source and I/V amplifier for HIPOT testing. It also has a programmable 0 to
50mA constant current I-source to measure the resistance of shunt bars and bridgewires.
Supplementary system components
For added versatility or as spares, a Model 2790 mainframe, 7751, 7752, 7753, and 7702
modules can be purchased separately. However, this special order may require a longer
delivery time and additional handling charges.
Test system
A typical test system for airbag inflators includes a Model 2790 that is controlled by a
PLC or PC, and a device handler/test station for the inflator. The Model 2790 has two slots
for switching modules. Modules for testing inflators include the Models 7751, 7752, and
7753. A Model 7702 module can also be used with the Model 2790.
NOTE Only one Model 7753 module can be installed in a Model 2790, and it should be
installed in slot 1. The 7753 can be installed in slot 2, but measurement accuracy
might be adversely affected because cards are always calibrated in slot 1.
Figure 1-1 shows a typical test system using a programmable logic controller (PLC) or a
PC. When using a PLC, communications with Model 2790 are done over the RS-232
interface. When using a PC, communications with the Model 2790 can be provided using
the GPIB or RS-232.
