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 ...

An option for all models of Spectrum Instrumentation’s M4i-44xx series of 14/16-bit PCIe digitizer cards furnishes eight additional digital input lines. Sitting beside the digitizer, the ...

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 ...

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 ...

Here's why I'm asking: I have a Denon AVR 3803 receiver. I like it quite a bit, except for one glaring (IMHO) omission; in order to use my Sennheiser wireless headphones, I have to run both analog and ...

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 ...

A hardware interface that accepts only digital signals. Contrast with analog input. For various examples, see plugs and sockets. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction ...

Programmable logic controller IO module. How hard is it to keep track of a binary electronic system? It can only be in one of two states: on or off, open or closed, 0 or 1. While that may be correct, ...

Designed for high-voltage protection in industrial control and monitoring applications, the PCIe-IDIO-24 PCI Express I/O card boasts 24 optically isolated digital inputs and 24 solid-state FET relay ...
