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 ...

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 ...

Addressing the requirements of power switching applications, the ADAM-6066 relay-output module includes Ethernet connectivity, an embedded web server for remote monitoring, and support for Modbus/TCP ...

AutomationDirect has released three new LS Electric XGB PLC models: two 16-point 2-axis motion PLC units and a 14-point relay output model. The 2-axis PLC versions support pulse/direction control from ...

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 ...

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, ...

I/O modules are building blocks of industrial control systems used in end equipment such as PLC (Programmable Logic Controllers), PAC (Programmable Automation Controller) and DCS (Distributed Control ...

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 ...

An edge server and  PLC controller for industrial automation, field comms and IoT edge applications by Sefra Labs are based ...
