1. Introduction
This manual contains information designed to familiarize you with the features and functions of the DI-4730 High
Voltage data logger and data acquisition system.
Features
The DI-4730 has the following features:
•
8 fixed isolated high voltage (±1000V Full Scale) differential inputs with software-programmable input
ranges of ±10mV, ±100mV, ±1V, ±10V, ±100V and ±1000V per channel
•
7 digital inputs protected to +30V
•
Up to 16-bit measurement resolution (dependent on sample rate)
•
Built-in USB, Ethernet, and Power over Ethernet (PoE) interfaces
•
Up to 160 kHz maximum throughput sampling rate
•
Adaptable low-pass filter per channel - corner frequency set as a function of sampling rate
•
A multi-purpose push-button for WINDAQ remote events and start/stop recording
•
Multi-color LED indication for easy notification of device status
•
Counter channel.
•
Frequency channel.
•
Free WinDaq data acquisition recording software. Purchase unlock code WinDaq/Pro for ChannelStretch
and Stand-alone data recording to removable flash memory.
•
Stand-alone option allows the user to configure a recording session through their PC then record data in the
field to removable flash memory via the USB drive port (without being connected to their PC). Stand-alone
data logging requires Unlock code to record more than 1 channel to removable flash memory.*
•
ChannelStretch™ Technology allows you to sync up to sixteen DI-4730, DI-4108, DI-4208, or DI-4718B
instruments in any combination with a total throughput of 480kHz or more (requires unlock code for each
device).*
•
Fully documented instrument protocol for programming the device in operating systems other than Win-
dows.*
*WinDaq/Pro required per device to use ChannelStretch™ when using WinDaq software. These restrictions do not
apply when programming the device yourself. This unlock code is also required to record more than a single channel
to removable USB thumb drive.
Analog Inputs
The DI-4730 features eight differential channel banana plug inputs located on the front panel for easy connection and
operation. Gain measurement ranges of ±10mV, ±100mV, ±1V, ±10V, ±100V and ±1000V are programmable on a
per channel basis.
Utilize the functionality of WINDAQ software to experience all the features built in to these cost-effective industrial
units. An Unlock Code is required to synchronize and record multiple units when using WinDaq software. There are
no restrictions when programming the instruments yourself.
