Introduction 1
USB-7230/7250
1 Introduction
1.1 Overview
The USB-7230/7250 USB-based digital I/O modules feature high
voltage ON/OFF control and monitoring, and isolation voltage sup-
ported up to 2500VRMS. The USB-7230 provides 32-channel iso-
lated digital I/O and 2-channel frequency/event counters, and
USB-7250 provides 8-channel isolated digital inputs, 8-channel
electromechanical relays, and 2-channel frequency/event coun-
ters.
The USB-powered USB-7230/7250 have removable screw-down
terminals for easy device connectivity, and the included multi-func-
tional stand fully supports desktop, rail, or wall mounting.
The USB-7230/7250 are suitable for industrial I/O control applica-
tions requiring high voltage and excellent protection. High isolation
voltage protects against damage from accidental contact with high
external voltage and eliminates troublesome ground loops. U-Test,
a free ready-to-use testing program, is included to enable opera-
tion or testing of all ADLINK USB DAQ series functions with no
programming requirement.
