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 ...

In this article, we highlight one of the most important architectural traits of new continuous-time sigma-delta (CTSD) precision ADCs: the easy to drive resistive input and reference. The key to ...

Switch-mode power supplies can use digital current-mode techniques for protection against peak currents, magnetic field "ratcheting," and input-voltage variations. Digital control of switch-mode power ...

Acromag has released another BusWorks Ethernet I/O module to simplify the task of interfacing data from virtually any analog sensor to a Modbus TCP/IP control/monitoring system. The new 958EN model ...

The importance of voltage drop in current sensing. High-accuracy current sensing hinges on the ADC. Specs and other features of the new isolated ADC. Current sensing is critical for enabling overload ...
