USB-1900 Series
1 Introduction
1.1 Overview
The USB-1900 Series of 16-bit 250 kS/s USB 2.0-based high-performance DAQ modules includes models USB-1901/1902, featuring four different voltage input ranges, and USB-1903, with
additional built-in precision current-to-voltage resistors capable of
direct measurement of current signal from 0 to 20 mA.
The series also delivers 2-CH, 16-bit analog output capable of up
to 1 MS/s update and programmable function I/O. The software
programmable function I/O supports a variety of functions including TTL digital I/O, general-purpose timer/counter, and PWM output. The USB-1900 Series’ analog input, analog output, and
function I/O are capable of functioning simultaneously at full
speed.
The modules are USB-powered and equipped with removable
screw-down terminals for easy wiring. The attached multi-functional stand can be used for desktop, rail, or wall mounting.
Suitable for mixed-signal tests, laboratory research, and factory
automation, the USB-1900 Series provides a significant single-board solution with optimum integration of multiple tasks at an
affordable price.
