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 I2C-16IO board is a 22-pin CMOS device that provides 16 bits of GPIO expansion using I2C bus. There are no external components required.The I2C-16IO board is a 22-pin CMOS device that provides ...

The isolated analog input module presented here is particularly suitable for industrial electronics applications. Sending analog signals from field sensors over long-distance cables is often difficult ...

Vmetro has announced a high-speed analogue input XMC module with the high speed I/O performance of the Virtex-5 FPGA. The AD1520 is a dual channel 1.5Gsample/s ADC XMC/PMC module. A National ...

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, ...

The following are some basic facts about input loop power sources: The input module usually isn't a loop power source. Although 120V is common for digital loops, other voltages are also used. There ...
