Sort the components into their voltage world first, from memory, before you flip back to check yourself. Then assign the network traffic, then write the Riverside note.
The system lives in two electrical worlds. High-voltage AC, typically 480-volt three-phase, feeds the big motors, the sorter drive, and the panels. Low-voltage DC, typically 24 volts, runs the controls. Mark which world each component below draws its power from.
| Component | 480V three-phase AC | 24V DC controls |
|---|---|---|
| The PLC I/O | ||
| The big motors | ||
| The MDR zones | ||
| The sorter drive | ||
| The sensors from Lesson 19 | ||
| The panels | ||
| The safety devices from Lesson 20 |
One line, from the reading: name the thing inside the control panel that turns the high-voltage feed into the 24-volt control domain.
One physical industrial network can carry both ordinary control and safety-rated control at once. Write what each protocol carries, in your own words, from the reading.
