High-density LXI switching matrix modules
High-density LXI switching matrix (60-553) is a 1024×4 dual bus 1-pole matrix in a compact 1U full rack width enclosure. The product has been designed specifically to support high relay closure counts to optimize its use with a digital multimeter (DMM) or source meter for checking for insulation problems between a single contact and all other contacts in the unit under test (UUT), requiring the closure of up to 1024 crosspoint relays.
The 60-553 LXI switching matrix is designed with a dual bus arrangement that allows the matrix to be divided into two smaller independent matrices, for example, two matrices of 512×4. The dual bus design features isolation relays; this also allows sub-matrices to be isolated from the main matrix when there are no closures on that sub-matrix, minimizing capacitive loading and maximizing bandwidth of the matrix. They can also be linked together to form larger matrices by cables and can be supplied as partially populated matrices from 256×4 in increments of 128×4.
User connections are provided on a 160-way DIN41612 connector that is fully supported by Pickering Interfaces range of connector accessories. Control is via an Ethernet connection that is fully compliant to Version 1.4 of the LXI standard.
Also available on the 60-553 LXI matrix is the company’s diagnostic test tool BIRST™ (Built-in Relay Self-Test). BIRST provides a quick and simple way of finding relay failures within the matrices.
