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, ...

The modules also reduce the per-point cost of digital I/O systems by providing up to eight times the number of I/O channels in the same amount of space. The SNAP-ODC-32-SNK and SNAP-ODC-32-SRC provide ...

PLC evaluation board applications for industrial process-controlsystems are diverse, ranging from simple traffic control to complexelectrical power grids, from environmental control systems ...

Pickering Interfaces, a provider of modular signal switching and simulation products for electronic test and verification, has announced four new industrial digital I/O families for PXI- and LXI-based ...

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 ...
