Real-time controllers operate in wider temperature range

The new CompactRIO controllers suit advanced measurement and control applications ranging in temperatures from -40 to 70degC. The NI cRIO-9023 controller has a 533MHz PowerPC processor, and the NI cRIO-9025 controller has an 800MHz PowerPC processor, as well as dual Ethernet ports for network programming, communication and expansion I/O. Both controllers work with the existing CompactRIO reconfigurable chassis, which features field-programmable gate arrays (FPGAs) that are programmed using the NI LabVIEW 2009 graphical system design platform. Using LabVIEW and CompactRIO, engineers can quickly implement custom analogue and digital control loops, with high-speed signal processing algorithms to meet advanced measurement application needs.

In addition to an extended operating temperature, the new CompactRIO controllers are available with a conformal coating. This is a specially formulated thin film material applied directly to circuit boards or circuit card assemblies and provides an impermeable seal to protect circuitry from humidity, moisture, mould, mildew, fungus, dust and corrosion caused by exposure to extreme environments. Application areas in which the conformal coating can provide protection include marine, railway, automotive, factory monitoring, fuel cell testing and oil and gas refining.
