USB-7230/7250
Isolated USB Digital I/O Modules
Introduction
The USB-7230/7250 USB-based digital I/O modules feature high voltage on/off control and monitoring,
and isolation voltage supported up to 2500VRMS. The USB-7230 provides 32-CH isolated digital I/O and
2-CH frequency/event counters. The USB-7250 provides 8-CH relay output (4 form C and 4 form A),
8-CH isolated DI, and 2-CH frequency/event counters.
The USB-powered USB-7230/7250 features removable screw-down terminals for easy device connectiv-
ity, and the included multi-functional stand fully supports desktop, rail, or wall mounting.
The USB-7230/7250 is suitable for industrial I/O control applications requiring high voltage and superior
protection. High isolation voltage protects against damage from accidental contact with external voltages
and eliminates troublesome ground loops. U-Test, a free ready-to-use testing program, is included to en-
able operation or testing of all ADLINK USB DAQ series functions with no programming requirement.
