Extended Voltage Range Adapter Series
Complete real-time control and data acquisition solutions for hydraulic and servo-hydraulic applications.
Extended Voltage Range Adapter Series
The EVRA Series from Genuen features 8-channel data acquisition modules for the NI FlexRIO platform that natively supports differential input signals up to ±300V. Combined with the NI FlexRIO FPGA card and a PXI chassis, the EVRA Solutions offer a capable and cost effective approach enabling the configuration of high performance data acquisition systems with extended voltage range coverage quickly and easily. The EVRA Solutions provide 8 channels of high resolution, extended voltage range inputs, scalability with PXI and PXI Express, and a fully programmable FPGA. The default configuration includes simultaneous real-time data correction delivering integral linearity performance better than 0.1% across the entire signal input range. Leveraging the FlexRIO architecture, every channel can be independently programmed.
EVRA Product Features
Using custom, real-time data analysis leveraging FPGA’s along with multiple 8-channel cards each with extended voltage front ends. The combined packages come pre-programmed with two different analysis solutions:

Edge Triggered Recording
Using a programmable trip level (up to 4 per channel) along with a programmable delay and a voltage reading. This is used to precisely characterize high voltage pulses that occur over a long period of time. Each event is time stamped with time and voltage level.

Windowing Triggered Recording
This method uses a programmable event window to trigger an event, then resets the event window (each event is time stamped). This is an easy way to characterize pulse patterns or step changes to a signal that may occur over long periods of time without continually recording the data.

Platform
Since the platform is based on the FlexRIO FPGA, custom data algorithms may be easily programmed. The power of the FPGA architecture manifests itself in a number of ways. These benefits include increased performance, time to market, cost, reliability and long-term maintenance. Taking advantage of hardware parallelism, FPGAs exceed the computing power of digital signal processors (DSPs) by breaking the paradigm of sequential execution and accomplishing more per clock cycle. Further, controlling inputs and outputs (I/O) at the hardware level provides faster response times and specialized functionality to closely match application requirements.
