In our previous issue, we noted that the first step in troubleshooting digital input modules is to verify the power source of each loop. If input power is missing, the causes can be such things as ...
Telecom and data-communications equipment commonly use small-formfactor pluggable (SFP) modules for the physical-layer interface. Also common in these systems is an I 2 C bus for the management data ...
Microcontroller-based systems with analog I/O can be simplified by modularizing them as stackable boards interconnected by a minimalist bus. The InterModule Bus (IMB) is a master-slave bus controlled ...
Solid-state relays are much smaller than corresponding single-pole relays. They are also faster, dissipate less power, and withstand a larger number of operations. And unlike electromechanical relays, ...
While learning about different types of vibration sensors for condition monitoring, I came across a cheap piezoelectric shock/tap/vibration sensor switch module hiding in a corner of my messy ...
