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 ...

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 ...

It's time to get a little more specific with what the PLC CPU controls: PLC I/O! This article will discuss discrete I/O, analog I/O and briefly introduce industrial communications protocols. We talked ...

Digital/binary sensors and switches are essential for signal monitoring and system control in industrial control, industrial automation, motor control, and process automation. All the sensors’ outputs ...

. These modules provide higher resolution for more precision in measurement and control applications. 8-channel input modules are available with input ranges of 0-20/4-20 mA and 0-5 V or 0-10 V. Four ...

Higher amperage relay output modules and an 8-point input simulator module are now available from AutomationDirect for the Click series stackable micro brick PLCs. The Click C0-04TRS-10 ($54.00) is a ...

WAGO 750 Series three functional safety I/O modules can be used with firm’s PFC controllers. Devices have four safe inputs along with either two safe outputs at 10 A/24Vdc, or four safe outputs at 2 A ...
