AutomationDirect has added discrete and analog I/O modules to the CLICK PLC line. Available 24 VDC combination discrete modules include eight-point DC input/eight-point DC sinking or sourcing output ...
The new CPUs feature two analog inputs and two outputs with ranges of voltage up to 5 VDC or current up to 20 mA. The modules include two built-in RS-232 and one RS-485 communication ports, and real ...
The Solves-It! analog plug-in programmable logic controllers (PLC) are targeted for small-system control and monitoring where speed, pressure, or other analog processes are involved. Just like its ...
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 ...
