Heavy AC or DC load switching modules take up single PXI slot

Pickering Interfaces has designed what it claims is the industry’s highest switching capacity in the smallest footprint for a solution based on electromechanical relays. Modules in the Model 40-166 PXI power relay family occupies a compact, single PXI slot form factor.

The family is available with single pole, single throw (SPST), single pole double throw (SPDT) or single pole, four throw (SP4T) switching configurations. It uses power relays that are suitable for switching loads up to 20A (SPDT and SP4T versions) or 30A at 277V AC (SPST). It can switch voltages up to 480V AC or 300V DC with a maximum power of 5500VA/600W (SPST configuration). Bandwidth performance is -3dB for a 30MHz (typical) power relay module.

“The single PXI slot envelope maximizes switching density within the chassis when compared to other high current modules aimed at the automotive and defence sectors,” explains Steven Edwards, switching product manager at Pickering.

Spare relay kits are available so that customers – with appropriate training – can repair devices on-site, to minimise system downtime.

The 20A and 30A versions feature connector keying, and VISA, IVI and kernel drivers are supplied for Windows.

Pickering’s connection division offers a range of cable accessories to support the 40-166 range. The modules are also supported by any PXI chassis or Pickering’s Modular LXI and LXI/USB chassis. The 40-166 carries a three-year warranty.

Pickering Interfaces designs and manufactures modular signal switching and simulation for use in electronic test and verification. It offers switching and simulation products for PXI, LXI, USB and PCI applications. The company also supplies cable and connector solutions, diagnostic test tools, application software and software drivers created by the in-house software team.

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.

Markets served include automotive, aerospace and defence, energy, industrial, communications, medical and semiconductor.
