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 connectivity, 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 enable
operation or testing of all ADLINK USB DAQ series functions with
no programming requirement.
