![]() A push button allows manual start/stop control over the recording process. The DI-4730 can record continuously using a circular buffer with pre-defined trigger conditions or a record-until-full approach supporting remote start/stop. For example, the rate input measuring engine speed allows rpm data to be acquired in lock-step with analog data.Ī USB drive is used to record data in stand-alone mode. This means that all enabled elements are acquired synchronously, which allows meaningful comparisons between analog and digital channels. The discrete, counter, and rate inputs are members of the same internal scan list used by the analog input channels. The rate input features a 50 kHz maximum measurement, allocated over twelve programmable measurement ranges (10 Hz to 50 kHz full scale.) The counter input provides 16-bit resolution and a terminal count value of 65,535. Two ports allow dual functionality as discrete inputs, or can be programmed as a counter or rate input respectively. ![]() The DI-4730 provides 7 digital inputs with protection to 25 V. All these features combine to provide pure data acquisition power at an unmatched price point. Rounding off the analog subsystem are low-pass filters per channel with automatic corner frequency selection as a function of sampling rate. Lower sampling rates deliver higher resolution readings. The front end feeds a variable resolution analog-to-digital converter that ranges from 12 to 16 bits as a function of sampling rate. ![]() With all eleven scan list items enabled (8 analog channels, one each counter and rate, and all discrete input ports in the remaining position) a total sample throughput rate of 220 kHz is supported.Įight analog input channels provide differential measurement flexibility and programmable ranges per channel of ☑0mV, ☑00mV, ☑V, ☑0V, ☑00, and ☑000 V full scale. Suitable for a wide range of analog and discrete measurements, the DI-4730, in tandem with the included WinDaq software, allows real time data acquisition, playback, and analysis performance that covers an incredibly broad array of applications in both laboratory and industrial settings. The two are functionally identical except that the DI-4730 supports both ChannelStretch™ channel expansion and stand-alone data logging to a removable USB flash drive (unlock code required). ![]() The DI-4730 is the next-generation of our very popular DI-730 series. *WinDaq/Unlock required per device to use ChannelStretch™ and to record more than a single channel to removable USB thumb drive.
