Yokogawa releases high-voltage ­analog input module

November 2018 Electrical Power & Protection

Yokogawa has announced the availability of the GX90XA-10-V1 high-voltage analog input module. This new product has been released as part of the OpreX Data Acquisition family of data collection and control solutions.

The GX90XA-10-V1 module enables Yokogawa 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. Yokogawa offers recorders and data acquisition system solutions for the collection and control of data as part of its OpreX Data Acquisition lineup. To meet market needs and comply with industry-specific requirements and standards, the company continues to add new I/O modules with enhanced functionality to this line-up.

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 analog 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.
