Analog Input Module features programmable sampling rates.
Press Release Summary:
As 16-channel VME ADC, V450 can acquire range of DC voltages and thermocouple measurements for all major thermocouple types. Each fully isolated channel can be configured independently, and arbitrary sets of channels can be synchronized for simultaneous data acquisition. In voltage mode, each channel acts as floating voltmeter with 24-bit resolution. In thermocouple mode, channels can measure thermocouples of types J, K, E, T, R, S, B, and N and resolve temperatures to 1/16°C.

Highland Technology Announced the Release of its New V450 Analog Input Module
San Francisco, Calif., June 5, 2006 - Highland Technology announced the release of its new V450 Analog Input Module.
The V450 16-channel VME analog-to-digital converter can acquire both a wide range of DC voltages and thermocouple measurements for all major thermocouple types. Each fully isolated channel can be configured independently, and arbitrary sets of channels can be synchronized for true simultaneous data acquisition.
In voltage mode, each channel of the V450 acts as a floating voltmeter, with 24-bit resolution over voltage ranges from +/-25mV to +/-250V. RMS noise is less than 5 PPM for most ranges at the 4 Hz sample rate, with 50/60Hz rejection of better than 80dB.
In thermocouple mode, channels can measure thermocouples of types J K E T R S B and N, and resolve temperatures to 1/16 degree C. Any of four platinum RTD inputs may be used to sense an external reference junction, or an onboard temperature sensor can allow direct connection to the front panel inputs. Any combination of channels can be assigned to any voltage or thermocouple range, and voltage and thermocouple measurements can be mixed freely.
Channels also feature programmable sampling rates up to 500Hz, switchable open input detection, and overvoltage protection to 350V regardless of configuration. Thermocouple loop resistance may be measured by user command; subsequent measurements are automatically compensated for burnout current errors without the error normally associated with open-thermocouple sensing. Relays are provided to reroute any input channel to a dedicated connector for calibration checks without disrupting field-wiring, and an automatic built-in self-test option is available.
The V450 is a 6U single-width VME board. Two front-panel D25 connectors interface to external devices. Each connector provides eight isolated signal inputs and two RTD inputs. Calibration of both input signals and RTDs can be checked via the front-panel D9 connector.
The V450 Analog Input Module is available immediately. For further information, contact Highland Technology.
