Valmet D20259 High Resolution Interface Module

The Valmet D20259 interface module provides eight isolated high-resolution, 16+ bit, general purpose bipolar analog inputs. This allows the IntelliLogger models IL-80 and IL-20 to increase the number of channels to a possible total of 128 inputs. The recently introduced IntelliLogger data logger is a self-contained, autonomous data collection and web server for monitoring, logging, and reporting temperature, pressure, flow, power, strain, and more. It is used in critical applications for global industry for remote monitoring, R&D, testing and process control improvements.

The Valmet D20259 controllers provide high computing performance and can easily achieve up to 832 MB/s of sustainable I/O bandwidth when bundled with the MXI-Express kit. These controllers feature standard Redundant Array of Independent Disks (RAID)-configured hard disk drives for Windows systems, making them ideal for high-end test and measurement applications. The new NI 8352 and NI 8353 rackmount controllers are based on Intel dual-core Core 2 Duo and quad-core Core 2 Quad processors, respectively. These multi-core processors are designed to perform multiple computational tasks simultaneously on different CPU cores.

The Valmet D20259 utilizes the multi-threaded nature of NI LabVIEW software, which allows test engineers to scale their applications based on the total number of cores available and benefit from faster, more flexible applications. These new controllers can also be used with a variety of RAID storage configurations featuring multiple SATA II hard drives that support RAID 0 (striping) and RAID 1 (mirroring) configurations RAID defines a data storage scheme that divides and/or replicates data across multiple hard drives to provide greater reliability and/or higher file I/O performance.
