AutomationDirect has expanded its AEM2G series compact limit switch line to include more electrical connection options. Four electrical connection types are now available for the AEM2G series of ...

Essentially, each pnp transistor compares a reference voltage on the npn emitter with the voltage across the lower limit switch circuit resistors R4, 5 and 6, directing current to the led if the limit ...

The purpose of this project is to present an alternative for the Arduino boards programming through a ladder diagram development environment. Similarly, it seeks to provide a new option for both ...
