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 ...

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 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 ...

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 ...

Higher amperage relay output modules and an 8-point input simulator module are now available from AutomationDirect for the Click series stackable micro brick PLCs.

Model NT2140 discrete AC power input modules have joined the BusWorks NT2000 Ethernet remote I/O family, and can sense on/off ...

[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… ...

Electronic engineers, developers and hobbyists looking for a fully featured Arduino Mega compatible PLC may be interested in a new Indiegogo campaign ...
