Product Features

8 Analogue Input Channels
Differential Analogue Input Configuration
Enhanced noise immunity and tolerance of common mode voltages.
12- to 16-bit Measurement Resolution
Armoured Inputs Absorb Mistakes
Both analogue and digital inputs are protected to 120 Vrms and 0-25 V dc respectively.
Fast 160 kHz Sample Throughput Rate
Stand-alone Data Logger Operation
Store data to flash drives at throughput rates up to 160kHz.
Pre/Post Tigger Storage to USB Memory
Set trigger levels to record up to 2G (combined) of pre- and post-trigger data (total file size of 4G)
Auto Re-Trigger
When using Triggered Storage, triggers can automatically reset, creating a new file with pre and post trigger data each time the trigger level is breached.
Supports ChannelStretch™ Channel Expansion*
Connect as many as sixteen DI-4108s , DI-4208s, DI-4718Bs, and/or DI-1120s to one PC. Synchronously acquire from as many as 128 and 112 analogue and digital channels respectively.
Seven Digital Input Ports*
Folds discrete I/O into the measurements process. Each bit is programmable as an input or as a switch and protected to 0-25 V dc.
Asynchronous Digital Switches
Control external processes seamlessly while acquiring data.
Counter Channel
Tallies the number of pulses applied. Useful for integrating rate information, like flow rate to volume, or simply the number of definable events.
Rate Measurement Channel
Measures pulse rate where frequency carries information. For example rpm or flow measurements.
Ready-to-run Software Support*
Provided with ready-to-run WinDaq software for point-and-click DAQ performance with a real-time display, disk-streaming recording, and playback and analysis.

* WinDaq/Unlock required per device to use ChannelStretch™ and to record more than four total channels when using WinDaq software.
