I-7055-NPN offers 8 channels for digital output and 8 channels for digital input. I-7055-NPN 8 channels for digital output each of which features Photo-couple isolation. supports sink type output with short-circuits protection. There are options for power on value and safe value for your consideration. Moreover, you can choose sink type or source type input by wire connections. All channels are able to be used as 16-bit counters. I-7055D-NPN has 8 LED indicators for DO channel status and 8 LED indicators for DI channel status. 4 kV ESD protection, 4 kV EFT protection, 3 kV Surge Protection for Power Input and 3750 VDC intra-module isolation are standard.
