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. The Click C0-04TRS-10 ($54.00) is a ...
With integrated diagnostics and override functions, PLCs have become easier to use and much less expensive. Before the automotive industry discovered the advantages of programmable logic controllers ...
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, ...
Expanding the SeaDAC family of USB data-acquisition devices, the SeaDAC PLC-16H digital I/O module combines high-current Form C relay outputs and optically isolated inputs. It includes eight SPDT high ...
Phoenix Contact has announced a new way of tackling the challenge of integrating a variety of signals in small, decentralised ...
The PuffinPLC Project is an effort to produce a Linux-based GNU Public Licensed Programmable Logic Controller (PLC). PLCs were developed in the 1960s to replace the complex electrical relay circuits ...
