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.
