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 ...
The Click PLC from AutomationDirect now includes three analog CPU models. They feature two analog inputs and two outputs with voltage ranges of up to 5 vdc or current up to 20 mA. The modules include ...
AutomationDirect's Productivity2000 programmable logic controller provides two independent single-ended 5-24 VDC inputs that accept up to 100kHz of pulse/direction and quadrature signals. The ...
Designers now have a way to reduce power, system cost, and size for programmable logic controller (PLC) digital-input subsystems, with the Corona (MAXREFDES12#) reference design. This design reduces ...
