Building Forward Together USB-7230/7250 Isolated USB Digital I/O Modules Features Card index switch selection USB 2.0, USB bus powered Programmable digital filter removes unexpected glitches from input channels Programmable DO/Relay initial status 32-CH isolated digital I/O (USB-7230) 8-CH relay output, 8-CH isolated DI (USB-7250) 2-CH frequency/event counters (USB-7230/7250) Up to 2500 VRMS isolation voltage Ready-to-use testing application (U-Test) provided Introduction Softare Suppor The USB-7230/7250 USB-based digital I/O modules feature high Windows 7/8 x64/x86 voltage on/off control and monitoring, and isolation voltage LabVIEW, MATLAB, C/C++, Visual Basic, Visual Studio.NET supported up to 2500VRMS. The USB-7230 provides 32-CH isolated U-Test 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. Ordering Information The USB-powered USB-7230/7250 features removable screw-down USB-7230 terminals for easy device connectivity, and the included multi- 2-CH isolated Digital I/O & 2-CH counter USB module functional stand fully supports desktop, rail, or wall mounting. USB-7250 The USB-7230/7250 is suitable for industrial I/O control applications 8-CH relay output, 8-CH isolated DI, & 2-CH counter requiring high voltage and superior protection. High isolation USB module 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 Optional Accessories operation or testing of all ADLINK USB DAQ series functions with no programming requirement.
