USB-2416 Series

24-Bit Multifunction Temperature & Voltage Devices

The USB-2416 Series offers high-resolution voltage or thermocouple measurements along with

digital I/O. Analog output functionality is available with the USB-2416-4AO.

Overview

The USB-2416 Series offers exceptional performance and accuracy for voltage and

temperature measurements.

Designed for the USB bus, each device provides up to 32 analog input channels

with 24-bit resolution, 8 digital I/O and two counter inputs. The USB-2416-4AO

also features four analog outputs.

Connect to the AI-EXP32 expansion device for an additional 32 channels of analog

input and 16 digital I/O lines.

Analog inputs are user-configurable for voltage or thermocouple input on a per-

channel basis.

Features

included

Supported Operating Systems

• Windows®

11/10/8/7/Vista®/

XP 32/64-bit

• Linux®

Analog Input

Each device provides 32 SE/16 DIFF ana-

log inputs, expandable to 64 SE/32 DIFF.

Software-selectable voltage input ranges

are configurable per-channel.

USB-2416 Series devices can sample ana-

log input channels at up to 1 kS/s. Open

thermocouple detection is automatically

enabled for thermocouple measurements.

Digital I/O

USB-2416 Series devices provide eight

digital I/O lines with read/write rates of

500 port or single bit reads per second.

EachDIOchannelisanopen-drain.Digital

outputs can sink up to 150 mA for direct

drive applications. The maximum sink

current is 150 mA per eight-channel bank,

or if all eight channels are used, 18 mA

(maximum) per channel.

Counter Input

Each device has two 32-bit event counters

that accept frequency inputs up to 1 MHz.

The internal counter increments when the

TTL levels transition from low to high.

Channel Expansion with

the AI-EXP32

The AI-EXP32 expansion device provides

an additional 32 SE/16 DIFF analog inputs

and 16 DIO lines. The AI-EXP32 supports

all analog/thermocouple input and digital

I/O features of the USB-2416 Series devices

to which it is connected.

The USB-2416 Series docks directly to the

AI-EXP32withanexpansionconnectoron

each device (see page 5). No additional

cable is required. Refer to the hardware

user’s guide for detailed information.

The AI-EXP32 receives power from the

connected USB-2416 Series device.

Analog Output

(USB-2416-4AO Only)

The USB-2416-4AO provides four 16-bit

analog outputs with a ±10 V output

range. The analog outputs can be updated

at a maximum rate of 1 kS/s (system-

dependent).
