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 ...

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 ...

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 ...

PLC Inputs and Outputs provides an overview of the main types of input/output modules and input/output devices, their primary functions, and their roles in a PLC process. In a PLC system, the ...

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 ...

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 ...

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 ...

Adam-6066 is a high-current relay output module that can be used for power switching applications. The unit's six relay output channels are rated at 250 VAC at 5 A and 30 VDC at 5 A. The channels ...

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 ...

A programmable logic controller (PLC) is an industrial solid-state computer that monitors inputs and outputs, and makes logic-based decisions for automated processes or machines. 1. The image above is ...

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, ...
