8-channel DC Solid State Relay Output Module using the DCON Protocol. The I-87066W module provides 8 DC Solid State Relay (SSR) Output channels. In comparison to electromechanical relays, SSR technology provides a faster response time and greater electrical endurance. The integration of DC SSR technology also eliminates the potential for arcing, bouncing, and switching noise. The I-87066W includes 8 LED indicators that can be used to monitor the ..
