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 ...

The AutomationDirect Productivity2000 programmable logic controller (PLC) is a modular, rack-based system with a full lineup of discrete, analog, and specialty I/O modules providing over 400 local I/O ...

Your first step is to verify that the module is the correct one for this control loop — unless this specific module has worked correctly before. Whether it has or not, you need to use a meter to test ...

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 ...

The TDAI-2210 also supports modular upgrades, such as a high-end analog module with an MM phono stage and balanced XLR inputs, or an HDMI 2.1 module with additional HDMI inputs and eARC support .

[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 ne… ...

A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and outputs, and makes logic-based decisions for automated processes or machines.

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 ...

Despite this, however, the standard PLC model permeates the structure: the PuffinPLC library offers PLC-like semantics for the modules that wish to use them. For example, inputs can only change at the ...
