The high-density 40 / 42-153 and 40 / 42-158 series can be thermally switched up to 1250va, providing very low path resistance and thermal offset.
On September 18, 2021, in clarkton, seaside, UK. As a leading manufacturer of signal switch and simulation solutions for electronic testing and verification, Pickering company of UK recently added two new products to 5A power relay module series, providing PXI and pxie versions. The new 40 / 42-153 and 40 / 42-158 power relay modules are suitable for switching large AC or DC loads, or for controlling large-scale external relays, contactors and solenoids. The new product is available in a variety of configurations, such as up to 50 SPST (single pole single throw) relays (153 Series) or up to 32 SPDT (single pole multiple throw) relays (158 Series). These new products are 5A switch modules with the highest density in the PXI market, and the number of channels provided is twice that of similar products.
The introduction of new products expands Pickering’s 5A switch module product line. The new 40 / 42-153 series PXI / pxie power relay module uses industrial power electromagnetic relay and supports various power test requirements. The new product offers a variety of different configuration options. The 153 series provides 18, 25, 36 or 50 SPST relays, while the 158 series provides 8, 16, 24 or 32 SPDT relays. The new module can thermally switch up to 5A signals under 250VAC voltage, and the maximum switching power is 150W / 1250va (153 Series) or 175W / 1250va (158 Series); Or cold switching up to 400VDC / 250VAC peak signal. In addition, these high-performance power relay modules also provide very low channel resistance of less than 35m Ω and thermal offset of only 3 µ V (typical value), and – 3dB typical bandwidth of 65Mhz (153 Series) and 100MHz (158 Series) respectively.
All versions of modules can be equipped with optional hardware accessories providing self-locking function. After the self-locking function is triggered, all relays with normal functions will return to the default non powered on (disconnected) state. The self-locking function is controlled by software, and when the self-locking function is activated, the user will be notified that the relay is about to be operated. This function is particularly useful when it is necessary to prevent relay operation before a hardware condition occurs. In addition, the self-locking function can also be used to de energize the relay.
“The new 40 / 42-153 and 40 / 42-158 PXI / pxie power relay module series are designed to maximize the switching payload, minimize the physical board space and keep the performance unaffected.” Steve Edwards, switch product manager of Pickering, explained the new product. “The new products only occupy one chassis slot and provide PXI and pxie control interfaces, which minimizes the number of slots required for PXI, pxie or LXI Chassis, enabling users to choose chassis more flexibly. These new products have a wide range of applications, including automotive, aerospace and national defense automatic test equipment (ATE) Systems, and general switching applications where customers build their own systems using non dedicated relays. “
The new product also provides the option of partial filling. By maintaining the front panel connection interface and pins of the existing 5A product, it is convenient for users to easily replace the control interface with pxie. In addition, the new product provides visa, IVI and kernel drivers for Windows operating system.
The new PXI / pxie power relay module comes with a three-year warranty. In addition, each module is equipped with a standby relay, which is convenient for users with certain PCB card processing experience to repair on the spot when the relay fails, so as to maximize efficiency and reduce system downtime.
