Description

DATAQ Instruments' DI-1000TC Series products are a line of instrumentation modules designed for temperature measurements using thermocouples. The unit is provided in 4- or 8-channel versions, and each channel may be configured in software to support one of seven thermocouple types: J, K, T, E, S, B, or R. Temperature measurements may range from -200°C to +1820°C (-328°F to +3308°F), depending upon thermocouple type. Each DI-1000TC thermocouple channel features a panel-mounted, miniature spade connector, and all input channels are electrically isolated from ground and each other up to 1000VDC, or peak AC.

Model DI-1000TC is designed for use across the entire spectrum of temperature measurement applications that use thermocouples. Its small size and wide measurement range make it a perfect temperature measurement device for laboratory applications. Its isolation feature allows it to be used in more demanding industrial applications that experience the large common mode voltages (off-ground measurements) that are typical of grounded thermocouples. Such measurement situations will prevent non-isolated instruments from making a measurement at best, or destroy them in the worst case.

Expandable

Multiple DI-1000TC units may be connected individually, or used as expansion units with any combination of other DI-1000 instruments to address any application-specific temperature measurement situation. For example, multiple DI-1000TCs may be connected to each other to provide unique 12, 16, 20, or other thermocouple channel counts.

Built-in RS-422 Interface

The built-in RS-422 interface allows DI-1000TC units to connect to any host PC through an inexpensive adapter via a USB port.

Isolation

The DI-1000TC's 1000VDC and Peak AC input-to-output and channel-to-channel isolation allows grounded thermocouple measurements.

High Accuracy and Resolution Design

Allows sharpened decisions with an overall accuracy of ±0.2%, and temperature resolution as fine as 0.08°C.

Portable

The DI-1000TC is provided in a small (13.81D × 10.48W × 3.81H centimeters; 5-7/16D × 4-1/8W × 1-1/2H inches) enclosure consisting of an aluminum base and all-steel wraparound.
