AI-ENABLED FRAME GRABBERS LAUNCHED PRODUCTS
ELECTRICAL & ELECTRONIC COMPONENTS
Now available from Impulse Embedded, Neousys Technology’s PCIe-NX156U3 and the PCIe-NX154PoE AI-enabled frame grabbers are powered by the NVIDIA Jetson Orin NX System-on-Module (SOM) and have the choice of either the 6-port USB or a 4-port PoE+ (Power Over Ethernet) camera interface. These are designed to withstand harsh environments by supporting a wide operating temperature of - 25˚C to +60˚C. Suitable for developers of machine vision and
automated inspection systems, these are said to make it easy to add the power of Nvidia Jetson to 19” rackmount and x86 Industrial Computer
platforms, shifting the AI processing load from the host computer and onto the card. The cards can therefore be an addition to existing systems by upgrading them to the latest image capture, pre-processing and inference technology. The NVIDIA Jetson Orin NX is the mid-range System-on-Module (SoM) from the latest Jetson Orin range, featuring NVIDIA Ampere architecture, offering a 1024 CUDA Core GPU, up to 16GB of LPDDR5 and up to 100 TOPS of INT8 computing power. Thanks to NVIDIA’s Jetpack software suite – a comprehensive solution for building
end-to-end AI accelerated applications – the software can be developed on any Jetson powered device and then seamlessly deployed onto these capture cards. The cards can also operate in standalone mode. The PCIe-NX156U3 has a USB interface offering six USB3.2 ports, each with 10Gbps bandwidth and up to 1500mA current for camera connectivity, whilst the PCIe-NX154PoE has four high-speed 2.5Gbps PoE+ ports, supporting a total of 50W for IP cameras, with both cards having software-programmable per-port power control.

RELAYS FOR EV CHARGERS AND PV-POWERED HOMES
Omron Electronic Components Europe has expanded its high-power switching capability with the addition of a low contact resistance model for the successful 2-pole contact type G7L-2A-X series relays. The compact (52.5 x 35.5 x 41.0mm) G7L-X series conforms to UK and IEC solar inverter standards, as well as applicable UL and VDE electrical standards. With a 6.0mm contact gap, the new G7L-2A-X-SI relay
provides low contact resistance of maximum 10mΩ and a rated load of 30A at 600V DC, or 25A at 1000V DC. These also feature an assisting magnetism circuit to help achieve a very quick switchover; and the relay contacts have been specifically designed to handle very high DC loads. Contact forms is 2-pole DPST and its 6.0mm contact gap ensures improved safety. According to the company, the G7L-X series enables reduced
charging time for vehicles and offers high capacity for residential energy storage systems and battery storage management. Capable of 6,000 operations at 600V DC, or 100 operations at 1000V DC, the relays provide higher capacity and low heat generation, the company explains. The new G7L-2A-X-SI relays are available now from Omron
Electronic Components Europe as well as its partners, authorised stockists and resellers.

WIDE-INPUT DC-DC CONVERTERS MEET RAIL INDUSTRY REQUIREMENTS
To meet the needs of rapidly-evolving railway infrastructure, GAIA Converter is expanding its range of high reliability and industrial grade wide-input DC-DC converters for rail applications. According to the company, the upgraded ultra-wide input portfolio achieves outstanding mean time between failures (MTBF) performance while satisfying the most demanding surge requirements, allowing a near seamless modular architecture offering from 5W to 500W. The latest additions include an input bus conditioner, a new device that can suppress
extreme surges in railway environments, and board-mount parts rated at 20W, 40W and 80W, with the added feature of 3kVAC reinforced safety isolation rating to IEC 62368-1. The ultra-wide input range for each part is 12 -160VDC, to include 24V, 48V, 72V, 96V and 110VDC nominals to meet EN 50155 and other rail specifications, as well as standards for common industrial applications. The input will also withstand 176VDC for 100ms to include the surge specified in rail standard NF-F 01-510 for 110VDC nominal, as well as the RIA12 specification of 168VDC for 20ms for 48VDC nominal. Surges to 385VDC for 20ms to specification RIA12 can be met with the additional input bus conditioner type FLHGI90, which also attenuates fast transients, provides reverse polarity protection and ensures compliance with EN 550121 EMC specification. Without the input bus conditioner, the parts can meet EN 55022 Class B EMI with a recommended external filter. Outputs available for each model are 2 x 5V, 2 x 12V or 2 x 15V, which are mutually
isolated and can be paralleled for higher current, placed in series for higher voltages or connected as ±bipolar outputs for maximum flexibility. Efficiency is typically 87% and case operating temperature range is from -40˚C to +105˚C without derating. Output power derates by just 25% for input voltages lower than 36VDC. Control functions include an on/off pin and output trim
which can vary the outputs -20% to +10%. In addition, each converter is offered in a fully potted low-profile metallic case: 35mm x 30mm x 10mm for the 20W part, 46mm x 36mm x 10mm for the 40W part, and 50mm x 44mm x 12.9mm for the 80W part.

BUSBAR SHUNT RESISTORS
New from TT Electronics is the EBW5216 series of shunt resistors for high current measurements in the hundreds of amps range. With a wide temperature range from -65 to +170˚C and AEC-Q200 qualification, the EBW5216 series is ideal for a spectrum of industrial and energy management applications, including welding power supplies, motor drives, battery management, energy metering and process control. The EBW5216 family is a compact complement to TT’s EBW8518 and is busbar-mounted in a 5216 size. It is an electron-beam welded resistance element sandwiched between large copper terminals with optional tin plating. The series offers values of 50 and 100µΩ at down to 1% tolerance, 150ppm/˚C TCR (measurement), 20ppm/˚C TCR (alloy), and
<1µV/˚C thermal EMF. The EBW5216’s ultra-low ohmic values reduce power loss and its low self-heating reduces
equipment temperature and improves reliability. Equivalent to Vishay WSBS5216, the EBW5216 series offers
a robust shunt with the option of pressed pin terminals at voltage sense points, permitting through-hole attachment to a printed circuit board (PCB). The optional through-hole voltage sense terminations optimise accuracy, allowing complete separation of the current path and voltage sensing. Featuring a short-term overload rating of 75W for 5s and up to 120J surge capacity, this robust solution is designed to withstand high inrush or switching surges.
