The I-7063A module provides 8 digital input channels and 3 AC SSR(Solid State Relay) output channels, and the I-7065A provides 4 digital input channels and 5 AC SSR output channels. All digital input channels can be used as 16-bit counters. In addition, the digital input channels can be selected either as sink- or source-type via wire connections. In comparison to electromechanical relays, SSR technology provides a faster response time and greater electrical endurance. The integration of AC SSR technology also eliminates potential for arcing, bounce, and switching noise. The I-7063AD provides 11 LED indicators and the I-7065AD provides 9 LED indicators that can be used to monitor the status of the digital input and SSR output. There are also options for configuring power-on and safe values. 4 kV ESD protection and 3750 VDC intra-module isolation are also provided to enhance noise protection capabilities in industrial environments.
