In the previous two issues of this newsletter, we looked at troubleshooting digital input modules. Basically, we looked for the presence or absence of a voltage. With analog modules, it's trickier ...

AutomationDirect's Productivity2000 programmable logic controller provides two independent single-ended 5-24 VDC inputs that accept up to 100kHz of pulse/direction and quadrature signals. The ...

In our previous two issues, we discussed troubleshooting digital output modules. Troubleshooting analog modules is a bit more complicated, for two reasons: Analog modules aren't on/off, as digital ...

New additions to the MAQ20 Industrial Data Acquisition & Control System are strain gage and frequency modules. Related To: Dataforth The MAQ20-BRDG1 strain gage module has four input channels and can ...

Beckhoff Automation has extended its range of IP 67 I/O modules with the newEP4374 EtherCAT Box. This flexible, moisture and dust-resistant I/O devicecombines two analog inputs and two analog outputs ...

[Scott Harden] has already produced some projects which measure analog inputs. But he’s got plans for more and wanted a base system for graphing analog signals. You can see the small board next to his ...

An overview of the hardware and software components of PLCs and their programming languages. A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and ...

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 ...

The PuffinPLC Project is an effort to produce a Linux-based GNU Public Licensed Programmable Logic Controller (PLC). PLCs were developed in the 1960s to replace the complex electrical relay circuits ...
