The M-7055U module provides 8 isolated channels for Digital Input and 8 isolated channels for Digital Output. Digital Input and Digital Output can be selected as either sink- or source-type via wire connection. All Digital Input channels are also able to be used as 16-bit counters. There are options to enable both power-on and safe values. The M-7055UD has 16 LED indicators that can be used to monitor the status of the Digital Input and Digital Output channels. The M-7055U(D) also provides ±8 kV ESD, ±4 kV EFT and ±2 kV surge protection, as well as 2000 VDC intra-module isolation to enhance noise protection capabilities in harsh industrial environments.
