Digital input serializers (DIS), the heart of digital input modules, must operate in harsh industrial environments. Voltage and current transients caused by electrostatic discharge, switching of ...

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 ...

Serial Peripheral Interface (SPI) output driver chips are popular with embedded designers because they provide multiple outputs without using any CPU I/O pins. This article explains how to adapt a ...

STMicroelectronics rolled out two high-speed digital-input current limiters that set new standards for circuit protection in factory automation. The SCLT3-8BQ7 and CLT01-38SQ7 provide industrial ...

Offering support for hi-res PCM, DSD, 7 digital inputs, and future upgradability, the McIntosh MDA200 D/A Converter warrants a serious look. 7 digital inputs and upgradability might not seem all that ...

Optoisolators—also called optocouplers or photoisolators—are widely used to provide galvanic (ohmic) isolation of digital-signal inputs and outputs in industrial environments, as well as in other ...

Digital TVs are getting thinner, wider and less expensive. But one important piece is still missing from several manufacturers’ models: the digital inputs that would enable new forms of entertainment.

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 ...
