Programmable logic controllers (PLCs) are an essential part of the automation sector, particularly factory automation. PLCs are classified as voltage and current inputs and convert real-world signals ...

The isolated analog input module presented here is particularly suitable for industrial electronics applications. Sending analog signals from field sensors over long-distance cables is often difficult ...

In the previous two issues of this newsletter, we looked at troubleshooting digital input modules. Basically, we looked for the presence or absence of a voltage. With analog modules, it's trickier ...

AutomationDirect has added more I/O expansion modules to its BRX Micro PLC product line. BRX I/O expansion modules add discrete and analog I/O to the BRX PLC system as needed to expand machine and ...

The MAQ20-BRDG1 strain gage module has four input channels and can interface to full, half, and quarter bridge sensors using four-wire or six-wire connections. All channels are individually ...

[Scott Harden] has already produced some projects which measure analog inputs. But he’s got plans for more and wanted a base system for graphing analog signals. You can see the small board next to his ...

When taking measurements from analog sensors located at long distances, voltage drops and noise can affect precision of the readings. Therefore, a voltage-to-current (V/I) module is needed to transmit ...

This full line of DIN-rail-mountable analog function modules can operate as a front-end for computers in various types of control systems. EZ-Circuit Analog Function Modules are packaged in plastic ...

The Raspberry Pi is a very capable device whose hardware has been pushed to the limit in all sorts of interesting ways. But even the most ingenious of experimenters have to agree on one point; it ...

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 ...
