Introducing the USB-2416
Overview: USB-2416 features
The USB-2416 is supported under popular Microsoft ® Windows ® operating systems. The USB-2416 is a
multifunction measurement and control board designed for the USB bus.
The USB-2416 is a full-speed (up to 1 kS/s), multiplexed 24-bit measurement system that provides up to 16
differential and up to 32 single-ended (SE) analog inputs. It offers software-selectable analog input ranges of
±20 V, ±10 V, ±5 V, ±2.5 V, ±1.25 V, ±0.625 V, ±0.312 V, ±0.156 V, and ±0.078 V.
It also protects your computer by providing a minimum of 500 VDC input isolation between field wiring and
the USB interface.
You can configure up to 16 of the analog inputs as differential thermocouple (TC) inputs. In thermocouple
mode, the USB-2416 includes built-in cold-junction compensation and open thermocouple detection.
You can add up to 32 single-ended or up to 16 differential channels by connecting the USB-2416 to an
AI-EXP32 expansion module. Each channel is software-configurable as single-ended or differential. You lose
one SE channel for each channel pair configured differentially.
The device has eight lines of digital I/O and two 32-bit counters. You can expand up to 24 DIO channels by
connecting the USB-2416 to an AI-EXP32 expansion module.
Six banks of removable screw-terminal blocks provide connectivity to the analog input channels, digital I/O
lines, and counter/timer channels.
