Control System parts and their functions
7 top-level parts · 8 parts in total · full bill of materials below
| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | Temperature Controller | 1× | Microprocessor controller holding chamber temperature within ±1 °C of the 4 °C setpoint. |
| 2 | LCD Panel | 1× | Status display |
| 3 | Defrost Controller | 1× | Controller running periodic defrost cycles without letting product temperature rise. |
| 4 | Bare PCB | 1× | Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it. |
| 5 | Relay | 2× | Electromechanical switch in which a small coil current closes or opens contacts rated for a much larger load, isolating control circuits from what they switch. |
| 6 | SMD Passive (R/C/L) | 1× | Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board. |
| 7 | Power Supply | 1× | Unit that converts mains or battery input into the regulated DC voltages a machine's electronics and actuators need. |
