PXI power relay switches voltages up to 480VAC or 300VDC

A new high-power relay PXI module that provides what is claimed to be the industry’s highest switching capacity in the smallest footprint for a solution based on electromechanical relays has been unveiled by Pickering Interfaces.

Occupying a compact single PXI slot form factor, the model 40-166 is available with SPST, SPDT or SP4T switching configurations.

It uses power relays that suitable for switching loads up to 20A (SPDT & SP4T versions) or 30A at 277VAC (SPST) and can switch voltages up to 480VAC or 300VDC.

Pickering’s 40-166 power relay modules are intended for switching heavy AC or DC loads or for controlling large external relays, contactors and solenoids.

The range is suitable for applications requiring switching of either mains voltage or DC and can switch up to 480VAC or 300VDC with a maximum power of 5500VA/600W (SPST configuration).

This latest module also offers significant bandwidth performance (-3dB) for a 30MHz (typical) power relay module.

Comments Steven Edwards, Switching Product Manager at Pickering: “The single PXI slot envelope maximises switching density within the chassis when compared to other high current modules aimed at the automotive and defence sectors. Spare relay kits are available, allowing customers – with appropriate training – to repair devices on-site, thus minimising system downtime. Of course, like all our switching products, the 40-166 carries a three-year warranty.”

The 20A & 30A versions of this high power module feature connector keying, and VISA, IVI & Kernel drivers are supplied for Windows.

Pickering’s connection division offers a range of cable accessories to support the 40-166 range, and the devices are supported by any PXI chassis or Pickering’s Modular LXI and LXI/USB chassis.
