IA-3118-U2i-P industrial high power high voltage monitor and control

The IA-3118-U2i is an industrial high power high voltage monitor and control device. This device includes an isolated USB communication port that provides the best RFI/EMI noise immunity and avoid any possible ground loop.

All isolated digital input channels are isolated from each other and are digitally filtered to ensure reliable operation in a noisy factory floor environment.

All relay contacts are individually protected by voltage suppressors to avoid RFI/EMI noise generation and to extend relays operation life time.

Software support

The IA-3118-U2i software packet includes Setting and Operation utilities DOT.net drivers, and open code software examples for fast system integration.
