HV, scalable LXI matrix module offers modular construction
Up to 300×4 connections are offered with the latest LXI matrix modules released by Pickering Interfaces. The 65-218, a 50×4, one-pole LXI matrix plug-in modules can be used in conjunction with the 65-200-002 LXI modular chassis to enable the construction of matrices of up to 300×4 in steps of 50×4.
Two variants are available, capable of delivering cold switching to 400V DC or 750V DC (1kV pulse) up to 1.0A (switching) or 2.0A (carrying).
The modular construction enables great flexibility, says Pickering Interfaces, as requirements evolve, additional plug-in modules can be added and the control software automatically detects the new configuration. The plug-in matrices are loaded into the chassis via the front panel, for ease of maintenance. The 400V version (model 65-218-101) can use the internal analogue bus of the 65-200 chassis to connect the 50×4 matrix plug-ins and form a larger matrix. Front panel connector interfaces on all 65-218 plug-in modules are via high voltage nine and 50-pin D-type connectors.
The 65-200 platform offers built-in scan list sequence stores with triggering capability, both of which can be used to increase the efficiency of test systems by allowing pre-defined test sequences to be loaded onto the unit and executed automatically.
The design of the modules has been optimised to minimise path resistance to less than 200mR per plug-in path with a thermal offset of less than 4.0 microV (typical).
“With a chassis height of just 2U, it is possible to create a scalable, high voltage switching solution using the 65-218 50×4 matrix modules while minimising the area required in the test system cabinet,” said Steve Edwards, switching product manager at Pickering.
The high voltage modules are suitable for deployment in aerospace testing applications as well as the automotive industry.
Accessory support includes Pickering’s diagnostic tools, built-in relay self-test (BIRST) and eBIRST switching system test. Both provide a quick and straightforward way of finding relay failures within the modules, says the company. Like all Pickering’s products, the modules come with a three-year warranty.
Pickering also offers a range of standard and custom interconnect accessories supporting the 65-218 modules.
Pickering Interfaces designs and manufactures modular signal switching and simulation for use in electronic test and verification. It offers a large range of switching and simulation products for PXI, LXI, and PCI applications. It also provides cables and connectors, diagnostic test tools, application software and software drivers created by its in-house software team.
Pickering’s products are specified in test systems installed throughout the world. Pickering Interfaces operates globally with direct operations in the US, UK, Germany, Sweden, France, Czech Republic and China, together with additional representation in countries throughout the Americas, Europe and Asia, serving the automotive, aerospace and defence, energy, industrial, communications, medical and semiconductor industries.
