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 ...

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 ...

A 50 percent reduction in size provides greater packing density for this certified failsafe I/O, which also has six isolated Hart analog inputs between channels and its backplane bus. It supports ...

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 ...

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 ...

Acromag QMC350 modules offer 20 input channels for high-speed, high-resolution analog-to-digital signal conversion. Flexible digital filtering with software calibration of system gain, offset, and ...

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 ...

Input/output (I/O) instruments provide inputs and outputs to data acquisition devices, programmable logic controllers (PLC), and other computerized machinery.As data acquisition products, I/O modules ...

Data input modules receive signals from devices such as sensors and often provide voltage and current excitation along with signal conditioning for subsequent analog-to-digital conversion. They plug ...

Designers of digital systems are familiar with implementing the 'leftovers' of their digital design by using FPGAs and CPLDs to glue together various processors, memories, and standard function ...
