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 ...

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 ...

This multi-channel analog output module TI Design with multiplexed single channel digital to analog converter (DAC) for programmable logic controllers (PLC) illustrates the design of low-cost, ...

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 ...

Schweitzer Engineering Laboratories, Inc. has announced new modules and protocols for its remote terminal unit or programmable logic control platform, the SEL-2240 Axion. Customers can now order ...

In the broad-brush view of the analog-to-digital converter (ADC) versus its complement, the digital-to-analog converter (DAC), there’s no doubt that the DAC has an easier functional challenge. What’s ...

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 ...
