Programmable logic controllers (PLCs) are widely used in industrial electronic systems. With the augmenting complexity of system, the reliability poses a crucial challenge in safety critical ...

Ladder logic diagrams are one of the most common ways to program a PLC (programmable logic controller), a device that controls industrial processes and machines. Ladder logic diagrams use symbols ...

This course introduces the programmable logic controller (PLC) and its associated applications. Topics include ladder logic diagrams, input/output modules, power supplies, surge protection, ...

As an example, the transistor-transistor logic (TTL) 7408 chip contains four, two-input AND gates in one integrated circuit (IC) package. These gates and other types on separate ICs can be wired ...
