Dissecting (and sibling-comparing) a scorched five-port Gigabit Ethernet switch
As the latest entry in my “electronics devices that died in the latest summer-2024 lightning storm” series, I present to you v3.22 (the company’s currently up to v8) of TP-Link’s TL-SG1005D five-port GbE switch, the diminutive alternative to the two eight-port switches I tore down last month. Here’s a box shot to start, taken from…
Design digital input modules with parallel interface using industrial digital inputs
Industrial digital input chips provide serialized data by default. However, in systems that require real time, low latency, or higher speed, it may be preferable to provide level-translated, real-time logic signals for industrial digital input channel. So, some industrial digital inputs sample and serialize the state of eight 24-V current sinking inputs under SPI or…
