i600/i601 USB data logger

May 26, 2017 Craig Nyssen News Comments Off

The i600/i601 USB Data logger is a 16 single ended or 8 differential channel data acquisition system connecting voltage, thermocouple, thermistor, RTD, load cell, strain gage, potentiometer, current and resistant sensors to the PC via USB. The i600/i601 USB data logger is a rugged, compact, USB powered and highly accurate data acquisition system providing 8 or 16 different sensor types without additional signal conditioning is required. The i600/i601 USB data logger runs on a variety of different software such as MATLAB and LabVIEW.

FEATURES

The i600/i601 USB data logger connects a windows computer to sensors and controls via analogue inputs, digital inputs and digital outputs.
The i601 product provides ±36V bank electrical isolation; whereas the less costly i600 connects I/O signal ground to computer ground. i60x receives power from USB bus.
16se/8di voltage input channels with extremely accurate 24-bit A/D converter
4x digital I/O (4mA sink/source, 0 to 3.3V)
Connect directly to sensors: voltage, thermocouple, thermistor, RTD, load Cell, strain gage, potentiometer, current, resistance

PRODUCT SUMMARY

This A/D module provides 16se/8di voltage input channels (Ch#1…#16), each of which are independently software programmable with Windows software that support the direct connection to many common sensor types
Voltage input range on each channel is independently software programmable to one of: ±20mV, ±40mV, ±80mV, ±150mV, ±300mV, ±600mV, ±1.2V, ±2.5V, ±5V, ±10V
Included is a mating Hd44 Female Connector & Cover. Alternatively, one can attach i600/i601 to the following optional wiring boxes: i510, i511, i512. If one is working with thermocouples, an i510 wiring box is required due to its internal cold junction compensation.
i600 and i601 are stand-alone USB data acquisition systems. No additional components, such as external power supply, are required. Included in the box: i60x Hardware Device, USB Cable, Software on CD, Mating Hd44 Female Connector & Hd44 Cover. For details, see the i60x Installation Guide.
Digitize at a maximum sample rate of 160K sample/sec for 1 channel, 12Ks/sec/ch for 2 channels, 6Ks/sec/ch for 4 channels, and 3Ks/sec/ch for 8 channels. For more details, see Voltage Accuracy.
Each channel provides the following software programmable parameters: A/D Signal-Averaging-Per-Point (0 … 100mSec), Sample-Rate (samples-per-second-per-channel), Digital IIR Filter (LowPass, HighPass, BandPass, or BandStop), Voltage Measurement Range (±20mV…±10V), Sensor Type, and Single-Ended or Differential Wiring
Excitation power (+3.3V ±0.2V, <80mA, 28mA per sensor max) is provided for sensors, along with other End User Power voltages. This 3.3V, which is referenced to instruNet Ground, is automatically readback by A/D when calculating sensor values.
The 4mA sink/source digital I/O port consists of 4 individual TTL-compatible lines (Ch#25…#28), each of which can be configured as: input or output bit When configured as an input, a channel can be used to sense a digital high (2 to 5.5 Volts) or digital low (0V to 0.8Volts). When configured as an output, a channel can be set high (e.g. >2V) or low (e.g. <0.8V). These I/O pins are short-circuit protected against high voltages up to 6.0V and down to -6.0
