The big space control
Contents |
Goals
- Lights can be switched using a web interface and regular light switches.
- Roofs can be opened and closed.
- Redundant: if the Arduino fails, the light switches remain working.
Hardware
What we have available
- A little under 100 industrial relays (Piet)
- Industrial electricity cabinet (Piet)
- Diodes and NPN heavy-duty switching transistors. (Koen)
- Cover for the big electrical cabinet (jaroslav)
Thanks to all who have contributed hardware!
What we need
- More electrical cable
Documentation
Schematic
The schematic to control just one lamp.
Relay layout
This layout is identical to the actual layout in the cabinet. Drawing coming soon.
| Relay # | Relay 00 | Relay 01 | Relay 10 | Relay 11 | Relay 20 | Relay 21 | Relay 30 | Relay 31 |
|---|---|---|---|---|---|---|---|---|

Wiring color codes
Lesson learned: adding new colors on the fly will result in chaos:
| Color | Function | Notes |
|---|---|---|
| Brow | 220VAC L1 | |
| Grey | 220VAC L1 | switched for outputs |
| White | 220VAC N | |
| Blue | +24VDC | except immediately at main 220VAC input |
| Red | +5VDC | for Arduino inputs |
| Black | Ground | light switches switch ground |
| UTP cable | I/O for Arduino |
INPUT UTP cable
It's the one with the YELLOW tape!
This cable feeds signals from the Arduino to the relays .1
| Pin # | Color | Function | Notes |
|---|---|---|---|
| 1 | Green | Relay 01 input | |
| 2 | Green / White | Relay 11 input | |
| 3 | Orange | Relay 21 input | |
| 4 | Orange / White | Relay 31 input | |
| 5 | Blue | Relay 41 input | |
| 6 | Blue / White | Relay 51 input | |
| 7 | Brown | Relay 61 input | |
| 8 | Brown / White | Relay 71 input |
OUTPUT UTP cable
It's the one with the RED tape!
This cable gives the Arduino feedback about the state of the relays .0
| Pin # | Color | Function | Notes |
|---|---|---|---|
| 1 | Green | Relay 00 output | |
| 2 | Green / White | Relay 10 output | |
| 3 | Orange | Relay 20 output | |
| 4 | Orange / White | none | Will be connected to R30 input with resistor |
| 5 | Blue | Relay 40 output | |
| 6 | Blue / White | Relay 50 output | |
| 7 | Brown | Relay 60 output | |
| 8 | Brown / White | Relay 70 output |
Software
The software is identical to the one in the small Spacecontrol.
