Fundamental of Digital IO and Power saving in 4G router iiot gateway
JOM! Lets Sembang AIoT episod 29
During the live session of Sembang AIoT 29, we discussed the application of Digital IO in Industrial IoT and presented power-saving solutions for remote data collection using cloud-based 4G routers.Digital IO systems represent a fundamental requirement in virtually all industrial IoT applications. Whether you need to monitor switch status, equipment status, count occurrences, measure frequencies, or control lighting, Digital Input and Output play a crucial role. There are two primary categories of Digital Inputs:TTL Input (0-5VDC):TTL inputs are typically non-isolated and are suitable for internal detection systems where external interference is not a concern.Isolated Digital Input (Wider Voltage Input):Isolated inputs are predominantly used in industrial systems where isolating the connected equipment is essential to ensure resistance to external surges or signal noise. In an IoT system, Digital Outputs are similar to Digital Inputs but can be categorized into three types:TTL Output (0-5VDC)Isolated OutputRelay Output (Isolated Electromechanical Outputs)
