When the relay is in SET, its corresponding LED lights. Latching relays also feature unchanged status even when the system powered off, making the PCIe-7256 suitable for critical applications requiring output status to be maintained even under fault conditions. All digital input channels are non-polar and optically isolated, and may be set for optional use of RC filter. The PCIe-7256 also features a change-of-state (COS) function generating interrupt when any digital input changes state.

  • Optical Test And Measurement

    AMS Technologies AG

    Any type of fiber optic interconnection requires its interfaces to be free of dust and scratches in order to reach the lowest transmission loss. Small, handheld and battery powered inspection tools are available from AMS Technologies for inspection of fiber optic connectors in the field as well as high resolution type microscopes suitable for use in a production environment for qualifying the endface preparation. Additional S/W tools can support the user in making a quick decision if a certain defect is acceptable or if the surface fault disqualifies it for further use. Small and lightweight test equipment for measurement of the transmitted power in an optical fiber is needed wherever technicians handle optical fibers. Our product portfolio comprises light sources for various wavelengths, power meters for the visible and infrared and integrated solutions for sources and meters as well as optical time domain reflectometers (OTDR) coupled with visible wavelength light sources for easy fault detection within a fiber optic link.

  • Laser Spectroscopic Motor Exhaust Gas Analyzer


    The MEXA-ONE-QL-NX is an analyzer for the direct, simultaneous real-time measurement of the four relevant nitrogen-containing exhaust gas components NO, NO2, N2O and NH3.The analyzer combines a light source based on the new quantum cascade technology (efficient lasers in the mid-infrared spectral region) with a precisely adjusted dual path cell to measure low concentrations with maximum sensitivity. The detection limit complies with current European legal requirements.Furthermore, the MEXA-ONE-QL-NX offers wide measuring ranges of up to 5000 ppm (for NO). By using extremely narrowband light sources and measuring under reduced pressure the cross-sensitivity to other exhaust gas components can be drastically minimized.The complete measuring system - including filtration - is specifically developed for the measurement of NH3 and thus guarantees a very fast NH3 rise time (T10-T90) of less than 5 seconds. The MEXA-ONE-QL-NX can be operated as a stand-alone analyzer or integrated into the MEXA-ONE software interface for user-friendly and simplified system operation.
