In our previous issue, we noted that the first step in troubleshooting digital input modules is to verify the power source of each loop. If input power is missing, the causes can be such things as ...

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 ...

The isolated analog input module presented here is particularly suitable for industrial electronics applications. Sending analog signals from field sensors over long-distance cables is often difficult ...

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 ...
