1. Introduction

I-7000 is a family of network data acquisition and control

modules. They provide analog-to-digital, digital-to-analog, digital

input/output, timer/counter and other functions. These modules can

be remote controlled by a set of commands. The basic features of

I-7021, I-7021P, I-7022 and I-7024 are given as following :

z 3000 VDC isolated analog output.

z Programmable PowerOn Value of analog output.

z Programmable slew rate.

z Software calibration.

The I-7021 is an analog output module with 12-bit resolu-

tion and current readback function. The I-7021P is similiar with I-

7021 but with 16-bit resolution. The I-7022 is the dual channel

version of I-7021. The I-7024 is a 4-channel analog output module,

and supports bipolar voltage output.
