PXI-8511, 1‑ or 2-Port, Low-Speed/Fault Tolerant PXI CAN Interface Module
780686-02
CAN Interface
1‑ or 2-Port, Low-Speed/Fault Tolerant PXI CAN Interface Module—The PXI‑8511 is a fault-tolerant Controller Area Network (CAN) interface for developing applications with the NI‑XNET driver. The PXI‑8511 excels in applications requiring real-time, high-speed manipulation of hundreds of CAN frames and signals, such as hardware‑in‑the‑loop simulation, rapid control prototyping, bus monitoring, automation control, and more. The NI‑XNET device-driven DMA engine enables the onboard processor to move CAN frames and signals between the interface and the user program without CPU interrupts, minimize message latency and freeing host processor time for processing complex models and applications.

Thumpers and Cable Fault Location
-
Cable testing can be broken down to different steps of the process, starting with a time domain reflectometer test to look for an incident signal on the line or, in some high resistance situations, VLF testing. These tests will identify a fault, allowing you to move on to pre-locating it. In some low resistance faults this will occur alongside the identification via the TDR.

Ground Earth Resistance Tester
2678X
-
Shenzhen Chuangxin Instruments Co., Ltd.
Ground Earth Resistance Tester verifies the integrity (continuity) of the protective bonding of the equipment (Class I equipment) designed to secure safety through the basic insulation and protective earthing. It is also called earth (ground) bonding test. If the continuity of the protective bonding is confirmed, we can conclude that the equipment has the requirements for preventing electric shock even if the insulation between the primary circuit and the accessible conductive section fails and a fault current flows through the distribution system.

Relay
The 40-195 is a 22 Channel Fault Insertion Switch, 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 different fault conditions on pairs of signals between the test fixture and the equipment under test: Open-Circuit, Short-Circuit between signal pairs, Short-Circuit between signal pairs and user applied fault conditions e.g. Power or GND. Relays in-line with the signal paths allow open circuit conditions to be simulated on either side or both sides of a signal pair. Relays between each channel pair enable adjacent signals to be shorted, and relays between signal paths and the "Fault" connection allow the application of external user applied fault conditions.
