The trend towards increased monitoring in industrial automation and process control requires input modules with higher channel densities. In these applications, 24V DC digital inputs (DI) make up the ...

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 ...

The MAX14626 current loop protector features a current-limit switch to prevent damage to the analog input module from sensor failure. The current-limit switch features a 25Ω (typ) on-resistance and ...

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, ...
