In previous issues, we have discussed troubleshooting input modules. In the examples, the output modules checked out OK. But what if they don't? As with input modules, output modules can be digital or ...

Safety-relevant output modules as well as a logic module with expanded functional scope have been added to modules already available. Fourteen different safety-relevant function modules, from a simple ...

Expanding the EtherStax series of Ethernet I/O modules from Acromag are two analog-output units offering 16 channels of current-output or voltage-output control signals with 16-bit D/A resolution.

Available in both SMT and through-hole packages, the 50-A PTH12040 and 60-A PTH04040 plug-in POLA-compatible power modules feature Auto-Track sequencing, which allows the outputs of multiple modules ...

Point of Load (PoL) dc-dc converter modules provide regulated dc power to a wide variety of loads. PoLs are small, efficient and relatively inexpensive, so their ability to provide common powering ...

In our previous issue, we said a digital output module could be tested by using the PLC logic to force the output on and off then and observing the module’s response. If the module doesn't respond, ...
