The GX90XA-10-V1 is part of the OpreX Data Acquisition family of data collection and control solutions that enables the recorders and data loggers to be used in performance evaluation tests for the development and production of electric vehicles (EVs), fuel-cell vehicles (FCVs), and plug-in hybrid vehicles (PHVs) as well as the on-board batteries used in such vehicles. Such tests typically require the measurement of multiple channels under high-voltage conditions.
Recorders and data acquisition systems (data loggers) are used on production lines and at product development facilities to acquire, display, and record data on temperature, voltage, current, flow rate, pressure, and other variables. For the development and production of EVs, FCVs, PHVs, and on-board vehicle batteries, performance evaluation tests involving the measurement of voltage levels in multiple battery cells must be performed. The batteries used in such vehicles can have hundreds of interconnected cells, and the voltage levels at all these points must be measured simultaneously. The test devices that are used must be capable of withstanding voltages of several hundred volts (high common mode voltage) that are typically applied between the measuring terminal and the ground.
The high-voltage analogue input module developed by Yokogawa allows the measurement of multiple channels under high-voltage conditions and is thus well suited for the development and production of rechargeable batteries as well as vehicles that use those batteries.
The GX90XA-10-V1 has two layers of insulation and can withstand a common mode voltage of up to 600 V ACrms or 600 V DC, and is capable of sampling data at intervals as short as 100 ms. With the GX and GP series recorders, the module can accept up to 450 inputs; with the GM10 data loggers it can accept up to 420. With capabilities such as these, the GX90XA-10-V1 is ideal for use in tests on production lines and at development facilities that evaluate the performance of vehicle batteries with multiple channels and under high-voltage conditions.
