The Click C0-04TRS-10 ($54.00) is a 4-point, 10A per point, isolated relay output module with four Form A (SPST) relays and 4 isolated commons. Operating voltage range is 6-24 VDC / 6-240 VAC. The ...

Does the module's output correspond correctly to its input? Determine that by forcing the PLC output to 10%, 25%, 50%, 75%, and 90% and measuring on the output terminals at the corresponding range.

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 ...
