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 ...
WIXOM -- The Wixom manufacturing electronics manufacturer Acromag has released new BusWorks XT Series multi-channel optocouplers and interposing relay modules that connect discrete field devices to ...
Wago's 4-channel digital relay output module features compact 12 mm housing, the 750-515 reduces the cost per channel while maximizing space in the control cabinet. As a component of the fieldbus ...
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 ...
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 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 ...
In our previous two issues, we discussed troubleshooting digital output modules. Troubleshooting analog modules is a bit more complicated, for two reasons: Analog modules aren't on/off, as digital ...
“These multi-channel discrete contact sensor and relay output modules offer a safe, isolated interface between high-energy field devices and sensitive control system I/O modules,” explained Don Lupo, ...
