24-Bit Multifunction Temperature & Voltage Devices

Analog Input

Each device includes 16 SE/8 DIFF analog

inputs which you can configure for volt-

age or TC input on a per-channel basis.

Eight software-selectable voltage input

ranges are provided. You can configure

these ranges on a per-channel basis from

±10 V to ±0.078 V.

When measuring TCs, configure analog

inputs in DIFF mode. All devices also

include open TC detection to identify

improperly working thermocouples.

Sample Rate

USB-2408Seriesdevicescansampleanalog

input channels at up to a 1 kS/s. Refer to

the hardware user’s guide for informa-

tion about how noise filtering affects the

throughput rate for analog inputs.

Analog Output

(USB-2408-2AO only)

The USB-2408-2AO includes two 16-bit

analog outputs. Each output has a ±10 V

range. Both outputs can be updated at

a rate of up to 500 S/s per channel; one

output can be updated at a rate of 1 kS/s.

Digital I/O

Eight digital I/O channels are included

with each USB-2408 Series device, and

you can read from or write to each indi-

vidual bit.

Counter Input

Two 32-bit event counters are provided

to count TTL pulses at read/write rates of

up to 500 Hz. The counters accept inputs

of up to 1 MHz.

Calibration

The USB-2408 Series is factory-calibrated

using a NIST-traceable calibration process.

Specifications are guaranteed for one year.

The USB-2408 Series also supports field

calibration for users to calibrate the device

locally with the InstaCal utility.

USB-2408 Series devices offer high-resolution voltage or thermocouple measurements along

with digital I/O and counter inputs. The USB-2408-2AO (shown here) includes analog output

functionality.

Overview

The USB-2408 Series are multifunction DAQ devices designed for highly-accurate

voltage or temperature measurements. Each device features provides up to 16

single-ended (SE)/8 differential (DIFF) analog inputs, 8 digital I/O, and two counter

inputs. The USB-2408-2AO also features two analog outputs.

Each device in the series offers 24-bit resolution for ultra-accurate voltage or ther-

mocouple measurements.
