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 ...

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 ...

Touted as the world’s first TUV SIL 3 certified Hart failsafe analog input module, the Simatic SM 336 is available for use with Simatic ET 200M I/O and PCS 7F process safety systems. July 1, 2008 A 50 ...

AutomationDirect's Productivity2000 programmable logic controller provides two independent single-ended 5-24 VDC inputs that accept up to 100kHz of pulse/direction and quadrature signals. The ...

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 ...

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 ...

ACCES I/O Products said the module comes in a small, rugged design suitable for embedded and OEM applications.

[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 ...

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 ...
