When a PLC is used primarily to replace relays, timers, and counters, it's hard to beat the simplicity and usefulness of ladder diagram programming. Their ability to accept programming in ladder ...

In the first two installments of this series, we discussed whether or not an old transmitter was even worth fixing, followed by some techniques I ve used to repair high-voltage power supplies. This ...

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

On the surface, a programmable logic controller (PLC) might seem like nothing more than a generic microcontroller, perhaps outfitted to operate in industrial settings with things like high ...

Most industrial facilities include electric motors that require overload relays for protection, control and monitoring purposes. The latest overload relays are often called motor management relays ...

As engineers, we often need to design a customized control system or interface to address a need which can”t be met with an off-the-shelf interface device. In the used-to-be days, we”d get a Bud box, ...

The RIO-47300 pocket PLC is an intelligent I/O controller that uses a RISC processor for handling I/O and logic. The RIO-47300 pocket PLC is an intelligent I/O controller that uses a RISC processor ...
