The IA-3118-E is an industrial, high power, high voltage monitor and control device. 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 This device includes an ethernet interface port with an IP address and can be locally expanded by Intelligent-Appliance RS-232 devices, carrying a unique device address each, sharing the same IP address. The IA-3118-E software packet includes Setting and Operation utilities DOT.net drivers, and open code software examples for fast system integration.
