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 ...

Programmable logic controllers (PLCs) are an essential part of the automation sector, particularly factory automation. PLCs are classified as voltage and current inputs and convert real-world signals ...

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 ...

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 ...

The BusWorks 965EN Input Modules interface thermocouple and millivolt signals directly to an Ethernet Modbus/TCP 10/100 network. The six-channel, inch-wide I/O modules operate independently of any bus ...

Electronic control modules (ECMs) are small, dedicated computers that control components and systems in vehicles or other machines. Automotive ECMs control the engine, the anti-lock braking system ...

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, ...
