Analog Input
When configuring your PowerDNA® Distributed I/O Cube or RACKtangle I/O chassis, you may choose from a wide variety of analog input boards (layers). All boards come factory pre-installed and calibrated. Boards are available with up to 25 input channels, up to 24-bit resolution and up to 250 ksamples per second. Regardless of your application, we're sure to have a board that will make the measurement you need.
The table below provides a brief overview of the currently available analog input boards. In the unlikely event you don't see what you need, please give us a call or send us an email. We are working on new boards all the time. The board you need might only be weeks away.
