PLC-Based System Works Where Single Loop Temperature Controllers Fell Short

In many applications, single loop temperature controllers are sufficient to provide control of heating and cooling. But in some applications, including the one detailed in this article, closely coordinated control among many temperature control loops is needed. In those cases and others, PLC-based temperature control can be the best solution. A meltblown machine, a melted…

Upgrading Pump Stations with PLCs

When relays and timer circuits get old, they cause problems. Replacing them with PLCs keeps pumps running smoothly. One of the most important jobs of a water distribution system is to reliably deliver water to its customers. At our water district in California, we had pumping stations (Figure 1) with relay-based controls that were more…
