Introducing the USB-1616HS-2

Overview: USB-1616HS-2 features

The USB-1616HS-2 is supported under popular Microsoft® Windows® operating systems. The USB-1616HS-2 board is a multifunction measurement and control board designed for the USB bus.

The USB-1616HS-2 provides either eight differential or 16 single-ended analog inputs with 16-bit resolution. It offers seven software-selectable analog input ranges of ±10 V, ±5 V, ±2 V, ±1 V, ±0.5 V, ±0.2 V, and ±0.1V. You can configure up to eight of the analog inputs as differential thermocouple (TC) inputs.

The USB-1616HS-2 has two 16-bit, 1 MHz analog output channels with an output range of -10 V to +10 V.

The board has 24 high-speed lines of digital I/O, two timer outputs, and four 32-bit counters. It provides up to 4 MHz scanning on all digital input lines1.

Six banks of removable screw-terminal blocks provide connectivity to the analog input channels, digital I/O lines, counter/timer channels, and analog outputs.

You can operate all analog I/O, digital I/O, and counter/timer I/O synchronously.

Software features

For information on the features of InstaCal and the other software included with your USB-1616HS-2, refer to the Quick Start Guide that shipped with your device. The Quick Start Guide is also available in PDF at www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf.

Check www.mccdaq.com/download.htm for the latest software version.

1Higher rates—up to 12 MHz—are possible depending on the platform and the amount of data being transferred.
