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 ...

The XT1230 and XT1240 models provide a 16-channel interface for single-ended analog current or voltage input signals with Ethernet/IP, Modbus/TCP, Profinet, or i2o peer-to-peer communication. They ...

Logic Beach introduces the ILIM-7 interface module, the first in a series of add-on expansion modules for the company’s IntelliLogger network-connected data-acquisition and alarming system. The ILIM-7 ...

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 ...

[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 ...

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 ...
