WORLD OF TEST
SMALL FOOTPRINT PARALLEL BOARD TEST SYSTEM
The i7090 massively parallel board test system from Keysight Technologies is a new category of automated test equipment designed to perform tests in parallel on multiple printed circuit board assemblies (PCBA) to achieve high-volume throughput which speeds time- to-market and reduces cost-of-test. Current systems on the
market only support up to four cores in parallel. Customers need to test and purchase more systems to meet manufacturing demands, incurring scale and infrastructure costs, a larger footprint and additional labour for support and maintenance.
The new test system supports
up to 20 cores in parallel with PCI eXtensions for Instrumentation (PXI) based in- circuit test capability, as much as five times more than most currently available systems. To expand functionality, Keysight OpenTAP support enables open platforms for integration of hardware. According to Christopher Cain
of Keysight, massively parallel computation cores enable modern computers to deliver breakthrough performance. The i7090 board test system brings a similar capability into printed circuit board assembly (PCBA) manufacturing test and
❱❱ High throughput multi-core massively parallel test system designed for multiple board testing
programming. “The i7090 has an innovative modular architecture that delivers breakthrough throughput in a small footprint,” he said. “It is infused with state-of-the- art Industry 4.0 automation and analytics to deliver unparalleled capability that can be optimised for a broad variety of high- volume PCBA manufacturing challenges.”
ACCURATE & STABLE FLUXGATE CURRENT MEASUREMENTS
Danisense has released its versatile series RCMH070IB+ residual current monitor (RCM). Suitable for monitoring the residual currents in electrical power systems without the need for fast system shutdown, the Type B/B+ RCM can measure DC and AC residual currents from 30mA to 2A RMS at frequencies of up to 100kHz, suiting it to a wide range of industrial applications, loads and generation sources. Significantly, the new RCM is compliant with the updated norm IEC62020-1. This means that it can be used for remote monitoring without the need to perform periodic onsite checks. Featuring a 70mm primary cable/busbar aperture and user- selectable settings for
frequency range, integration time and rated residual operating current, the RCMH070IB+ RCM also features an analogue 4-20mA output. This represents the real-time true RMS (TRMS) value of the measured residual current for
interfacing to, for example, a PLC. Additionally a free potential
relay output (NO/NC) with user- selectable rated residual current limit can be used to provide a warning or even system shutdown if the TRMS residual
current measurement exceeds the preset value. An LED provides a visual indication of the status of the relay output. Built-in test and external test controls are provided for regular testing of the RCM. The RCMH070IB+ requires only a single 24V DC power supply. Loic Moreau, vice-president of
marketing at Danisense said: “These new RCMs use our Fluxgate current measurement technology with fixed excitation frequency to provide enhanced accuracy and stability. Applications include condition-based monitoring of insulation health; high voltage insulation testing; mission- critical installations in data centres and medical facilities, DC power systems
