PXI/PXIe Fault Insertion Switch, 64-Chan 2A, N/C Through Relays, Fault Buses on M & U

The 40-190C-112 (PXI) and 42-190C-112 (PXIe) are fault insertion switches with 64 channels. They are part of a range of modules available with 74, 64 or 32 channels and are primarily designed for the simulation of fault conditions in automotive & avionics applications involving the reliability testing of safety critical controllers. They have the ability to insert 3 different fault conditions between the test fixture and the equipment under test:

• Open-Circuit
• Short-Circuit between UUT connections
• Short-Circuit to other signals such as Power, Ignition & Ground via Fault Insertion Bus

Through relays on each channel enable signals to the UUT to be held open-circuit. The module has two Fault Insertion Buses that allow any channel to be shorted to any other channel also enabling connection to an external fault condition. A four channel multiplexer on each bus allows an external signal such as Power, Ignition or Ground to be selected as the fault condition. Additionally, switched signal lines (Monitor1 & Monitor2) allow direct monitoring of the fault buses with a DMM.

The module has separate fault bus connections on the UUT side and test equipment side of the through relays - see schematic diagram in the data sheet.

The through relays of the module are normally closed in the default (power off) condition, giving an un-interrupted path between the test fixture and the equipment under test. All the fault insertion relays are normally open in the default condition.
