Does the module's output correspond correctly to its input? Determine that by forcing the PLC output to 10%, 25%, 50%, 75%, and 90% and measuring on the output terminals at the corresponding range ...

New AC and DC discrete I/O modules include 8-point, 100-120 VAC input and output modules, 8- and 15-point, 3.3-24 VDC input and output modules and high-density, 32-point,12-24 VDC input modules. The I ...

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 ...

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 ...

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 ...

There are various approaches to developing programmable logic controller (PLC) applications using experimental techniques. Modifying existing PLC ladder logic programs is another common approach ...

Pickering Interfaces, a provider of modular signal switching and simulation products for electronic test and verification, has announced four new industrial digital I/O families for PXI- and LXI-based ...

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 ...
