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 ...

This high speed digital output module TI Design for programmable logic controllers (PLCs) illustrates the design of low-cost, simple high speed single-ended digital output module using standard low ...

Designed for use with the vendor’s SNAP Ethernet I/O systems, the SNAP-ODC-32-SNK and SNAP-ODC-32-SRC 32-channel digital output modules offer new levels of density for applications with high digital ...

Designed for use with Opto 22 SNAP Ethernet I/O(tm) systems, the new SNAP-ODC-32 modules offer new levels of density for applications with high digital output point counts, or that require more than ...

ABB was chosen to supply advanced automation, electrical and digital solutions for ADNOC’s all-electric Ruwais LNG project.

Here’s the reference schematic of the digital power supply module. As explained in the first installment of this serial article, dc output voltage and current levels are constantly monitored (and ...

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, ...
