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 ...

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 ...

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 ...

The 8B50/51 analog voltage input modules have a filter bandwidth of 20 kHz, significantly larger than the 1 kHz bandwidth of earlier models. Accuracy is specified at ±0.10%, and linearity at ±0.05%.

Does the module's output correspond correctly to its input? Determine that by forcing the PLC output to 10%, 25%, 50%, 75%, and 90% and measuring on the output terminals at the corresponding range ...

[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 ...

Measuring 6.2-mm wide, the IMS interface modules handle simple analog signal conversion chores in space-constrained designs. The modules convert current and voltage signals from a wide range of ...
