M3Z-AEX (Item 827), M4-AEX (Item 825)
Each Expansion Module adds 128 Test Points
M3Z, M4 Expandable to 2560 Test Points
This photo shows three Attached Expansion Modules (AEX) connected to the Control Module of a low voltage tester. The system pictured here provides 512 test points. When in use, you would attach 64-conductor flat cable to the headers on each expansion module. The flat cable would then extend to a custom-designed fixture or mating harness accommodates your multi-headed cable or wiring harness. You may also replace the two CB15 boards shown in the photo with 64-conductor flat cables. We can supply pre-assembled and tested sections of flat cable with 64-pin sockets (Item 854) if you would prefer not building them yourself.
Use our QuickMount™ fixtures if you need to interface with our connector board test interface fixtures.
You may order your system with the number of modules you need now and add more modules at a later date. A computer is required even though one is not shown in this photo.
Note: Adding expansion modules to an M3 or M4 series tester requires recalibration! Calibration is included in the purchase price.
Field installation is not recommended for M3 or M4 series testers, but is possible - requires calibration kit, Item 717SC.
