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 ...

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 ...

[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… ...

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 ...

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.

In this design the industrial digital-input serializer (U1) translates, conditions, and serializes the 24V digital output of sensors and switches to CMOS-compatible signals required by ...

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 ...
