PXI Dual Bus 74-Chan 2A Fault Insertion Switch, N/O Through Relays - 40-190B-302
The Dual Bus, 74 Channel PXI Fault Insertion switch is part of our family of 2 Amp fault insertion solutions, The range includes modules with 74, 64 or 32 channels and single or dual fault buses. This version has normally open through relays, so in the default state, there are no paths between inputs and outputs for any signal channel. It is primarily designed for the simulation of fault conditions in automotive & avionics applications involving the reliability testing of safety critical controllers. It is designed to be able to insert three 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. Fault Insertion Buses allow any channel to be shorted to any other channel and also enable any channel to be connected to an external fault condition. The module is available with either one or two fault buses. A 4-channel multiplexer on each bus allows an external signal level such as Power, Ignition or Ground to be selected as the fault condition. Additionally, switched signal lines allow direct monitoring of the fault Buses with a DMM. Supported by eBIRST eBIRST switching system test tools simplify switching system fault-finding by quickly testing the system and graphically identifying the faulty relay.
