i423 Product Overview The i423 card plugs into a 4 to 16 slot instruNet i4xx Card Cage, which in turn attaches to a Windows computer 6di Voltage Input Channels 4x Universal Digital I/O (20mA sink, -10V..30V) Connect Directly To Sensors: Voltage, Thermocouple, Thermistor, RTD, Load Cell, Strain Gage, Potentiometer, Current, Resistance, Accelerometer Additional i43x A/D module required to measure voltages Amplifier/Filter outputs made available at Hd44 connector for end user monitoring Product Summary This Amplifier (not A/D) module provides 6 differential voltage input channels (Ch#1/2...#11/12)40 , each of which are independently software programmable with Windows software that support the direct connection to many common sensor types This module does not contain an A/D converter, and therefore internally routes measured voltage to an i43x A/D module anywhere in card cage. At least one i43x must be installed in order to measure a voltage with this module. Each of the 6 differential channels support the direct connection to the following sensor types (click for Wiring Diagram and Setup Instructions): Voltage, Thermocouple, Thermistor, RTD, Load Cell, Strain Gage, Potentiometer, Current, Resistance, Accelerometer Each channel provides several independent analog low pass filter options: 0.006KHz / 2poles, 4KHz / 2poles, or FullBandwidth Voltage input range on each channel is independently software programmable to one of: ±5mV, ±10mV, ±20mV, ±40mV, ±80mV, ±300mV, ±600mV, ±1.2V, ±2.5V, ±5V, 0 to 40mV, 0 to 80mV, 0 to 2.5V, 0 to 5V Each channel provides the following software programmable parameters: A/D Signal-Averaging-Per-Point (0 ... 100mSec) , Sample-Rate (samples-per-second-per-channel) , Analog Low Pass Filter (0.006KHz / 2poles, 4KHz / 2poles, or FullBandwidth)2, Digital IIR Filter (LowPass, HighPass, BandPass, or BandStop) , Voltage Measurement Range (±5mV...±5V) , and Sensor Type Each input channel passes through it's own amplifier with a software selectable voltage gain of 1 or 64, and optional analog low pass filter. After this treatment, these are made available at Hd44 connector pins #17..#22 for purposes of end user monitoring, in addition to possible internal digitizing by A/D. Each channel provides optional digital IIR lowpass, highpass, bandpass and bandstop filters with independent software programmable cut-off frequency, minimum dB stopband attenuation, maximum dB passband attenuation, and filter type (e.g. Elliptic, Chebyshev B, Chebyshev S, and Butterworth). Number of poles/zeros (i.e. "filter order") is programmable between 2 and 32 . Excitation power (+3.3V ±.2V, 2V) or low (e.g.

i460 Product Overview The i460 card plugs into a 4 to 16 slot instruNet i4xx Card Cage, which in turn attaches to a Windows computer 12x Universal Digital I/O (20mA sink, -10V..30V) 16x Digital I/O (200mA sink, -10V..30V) Product Summary The 20mA sink digital I/O port consists of 12 individual TTL-compatible lines (Ch, #1...#8), each of which can be configured as: digital input bit, digital output bit, control output, clock output43 . When configured as an input, a channel can be used to sense a digital high (2.1 to 30 Volts) or digital low (-10V to .65Volts). When configured as an output, a channel can be set high (e.g. >2V) or low (e.g. 2V) or low (e.g.

MODEL i500 ANTI-ALIASING LOW PASS FILTER The i500 anti-aliasing low pass filter provides the following features: 8-Pole analog low pass butterworth filter daughterboard, ideal for anti-aliasing End user installs between 1 and 6 filter daughterboards onto each i423 card, one daughterboard per channel Maximum of 35 filtered channels per system Sold in packages of two filters per product, each is 1.7 x 0.6 inches (4 x 2 cm) i500 analog filter provides extremely low ±0.01dB maximum passband ripple for Fin/Fc ≤ 0.5. If one uses further oversampling, digital filtering and desampling; then passband ripple is ±0.002dB for Fin/Fc ≤ 0.8 due to the accuracy of a 30-pole digital filter. i500 analog filter provides stopband attenuation of ≥ 76dB for Fin/Fc ≥ 3 Signal first passes through i423 signal conditioning amplifier before reaching i500 analog filter; therefore, one can attach directly to the following sensors: Voltage, Thermocouple, Thermistor, RTD, Load Cell, Strain Gage, Current, Resistance, Accelerometer 4 different filter products, each with different cut off frequencies: 380Hz, 1KHz, 3.3KHz, 10KHz. However, further digital processing provides other cutoff frequencies lower than these. For example, with an i500 Fc=1KHz analog filter one can digitize at ANY sample rate less than 2Ks/sec/channel and have a DIGITAL low pass filter provide anti-aliasing.
