I-7051 is intelligently designed to provide signal conditioning system monitoring and safe value settings. I-7051 is a cost-effective solution for a wide range of valuable industrial control signals and systems. The DCON utility can help users to configure and test I-7051(16-channel Isolated Digital Input) modules. Plenty of library functions and demo programs are provided to let users develop programs easily under Windows, Linux and DOS operating systems. Users may mount the modules on a DIN rail, panel or wall. Modules have a screw-terminal block to connect to the signals.
