An industrial setting a plc is not simply “plugged into a wall socket”. the electrical design for each machine must include at least the following components. transformers – to step down ac supply voltages to lower levels power contacts – to manually enable/disable power to the machine with e-stop buttons terminals – to connect devices fuses or circuit breakers – will cause power to fail if too much current is drawn grounding – to provide a path for current to flow when there is an electrical fault enclosure – to protect the equipment; and users from accidental contact
