It uses power relays suitable for switching loads up to 20A (SPDT and SP4T versions) or 30A at 277VAC (SPST) and can switch voltages up to 480VAC or 300VDC.
Pickering's 40-166 power relay modules are designed to switch heavy AC or DC loads or to control large external relays, contactors, and solenoids. The range is suitable for applications requiring mains or DC voltage switching and can switch up to 480VAC or 300VDC with a maximum power rating of 5500VA/600W (SPST configuration). This latest module also offers significant bandwidth performance (-3dB) for a 30MHz (typical) power relay module.
According to Steven Edwards, Pickering's Switching Product Manager: "The single-slot PXI module maximizes switching density within the chassis compared to other high-current modules intended for the automotive and defense sectors. Replacement relay kits are available, allowing customers—with proper training—to repair the devices on-site, minimizing system downtime. Of course, like all our switching products, the 40-166 comes with a three-year warranty."
The 20A and 30A versions of this high-power module feature a keyed connector, and VISA, IVI, and Kernel drivers are supplied for Windows. Pickering's Connections division offers a range of cable accessories to support the 40-166 range, and the devices are compatible with any Pickering PXI chassis or modular LXI and LXI/USB chassis.
