1 Introduction
1.1 Overview
The USB-7230/7250 are USB-based digital I/O modules, featuring
high voltage ON/OFF control and monitoring, and isolation voltage
supported up to 2500V
isolated digital I/O and 2-channel frequency/event counters, and
USB-7250 provides 8-channel isolated digital inputs, 8-channel
solid-state relays, and 2-channel frequency/event counters.
The USB-powered USB-7230/7250 have removable screw-down
terminals for easy device connectivity, and the included multi-functional stand fully supports desktop, rail, or wall mounting.
The USB-7230/7250 are suitable for industrial I/O control applications 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 operation or testing of all ADLINK USB DAQ series functions with no
programming requirement.
. The USB-7230 provides 32-channel
RMS
