USB-7250

Introduction

The USB-7230/7250 USB-based digital I/O modules feature high voltage on/off control and monitoring,

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.
