1. Introduction
CB-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 CB-7021, CB-7021P, CB-7022 and CB-7024 are given
as following:
l 3000 VDC isolated analog output.
l Programmable PowerOn Value of analog output.
l Programmable slew rate.
l Software calibration.
The CB-7021 is an analog output module with 12-bit reso-
lution and current readback function. The CB-7021P is similar with
CB-7021 but with 16-bit resolution. The CB-7022 is the dual channel
version of CB-7021. The CB-7024 is a 4-channel analog output
module, and supports bipolar voltage outputs.
