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 ...

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 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 ...

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 ...

Common features are eight differential analog inputs (armored to withstand up to 120 VRMS) and seven bidirectional discrete ports. Two ports can be programmable as a counter or frequency input. The ...

An experienced circuit-design EE once clarified his view of the hierarchy of IC-vendor design support: High-performance, feature-rich ICs were good, application circuits were better, but complete ...
