High-Voltage High-Speed Data Logger DI-4730 from DATAQ

Description

The DI-4730 High-Voltage High-Speed Data Logger from DATAQ is the next-generation of the popular DI-730 series data logger. This latest model includes the option of channel expansion, and stand-alone capability using a removable USB flash drive (unlock code required).

Product Features

8 Analogue Input Channels
Measure as many as eight system variables at once with programmable ranges per channel of ±10mV, ±100mV, ±1V, ±10V, ±100V, ±1000V full scale with channel-to-channel and input-to-output isolation. Channel-to-channel isolation protects delicate control circuits, computer equipment, and personnel from high common mode voltages.
12- to 16-bit Measurement Resolution
Fully Isolated Inputs
Analogue inputs are protected to ±1000V input-to-output and channel-to-channel. Digital inputs are protected at 0-25 V dc.
Fast 160 kHz Sample Throughput Rate *1
Stand-alone Data Logger Operation (only with Stand-alone / SA Enabled Option)
Store data to removable USB flash drives.
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.
Comprehensive Published Protocol
Program in any environment or operating system with our fully documented and comprehensive protocol document. Numerous programming examples are available to help programmers of any level get up and running as quickly as possible.
Supports Channel Expansion *3
Connect up to 16 DI-4108s , DI-4208s, DI-4718Bs, and/or DI-4730s to one PC. Synchronously acquire up to 128 analogue and 112 digital channels.
7 Digital Input Ports
Counter Channel
Rate Measurement Channel
USB, Ethernet, and PoE Interfaces Included
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.

Supplied with: a 6-foot USB cable, a 5-foot Ethernet cable, a power supply and adapter, a screwdriver for digital input signal connections, and a USB thumb drive with WinDaq software.

*1 160,000 S/s in USB mode; 100,000 S/s in Ethernet mode.

*2 160 kHz stand-alone dependent on storage card type – refer to the Specifications Sheet

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