|A Full-Featured Signal Conditioner||
IRIS-SC is a versatile dual-channel signal conditioner. Serial ASCII data are output as either RS-232 or RS-422(485) signals for recording by an external terminal or computer. Important features are firmware-controlled and user-selectable. These include output data rates and formats, signal averaging autozero (nulling), and internal data storage (logging). Several output data formats are provided, all of which include X tilt, Y tilt, Temperature, and Serial Number information.
|A Powerful Control Device||
The firmware on the standard IRIS board has 5 user-programmable thresholds. When a tilt measurement is taken, it is compared to each of these thresholds: +X tilt, -X tilt, +Y tilt, -Y tilt, and tilt in any direction. If the measurement exceeds one or more of the thresholds, the corresponding output pin(s) in the H3 connector, is set high (5V), as shown below. If the threshold is not exceeded, the output remains at 0 Volts. The reference angle for the threshold measurement is selected using the autozero command. Threshold checking may be turned off with a single firmware command when it is not needed
IRIS-SC Digital Signal Conditioning Card
The IRIS-SC digital signal conditioning card is a powerful control device designed for use with all Jewell miniature tilt sensors. Output is ASCII RS-232 or RS-422(485) serial. Standard firmware includes five user-programmable alarm/trigger thresholds for tilts tilt switch/control applications. When a selected threshold is reached, the circuitry sets the output high
on one of the pins in the H3 control connector. Other firmware features include user-programmable data output rates, sample averaging, autozero (nulling), and baud rate. The IRIS-SC can also log up to 22,000 samples to internal memory for data dump/download on user command.
All IRIS-SC units include calibration when ordered with Jewell miniature tilt sensors (specify calibrated range on order).
