### Features
- Read a TPR280 pirani gauge (0-10V analog input)
- 8x relay outputs for
- Roughing pump interlock
- Diffusion pump interlock
- Emulate _Pump-Down_ push button
- Emulate _Vent_ push button
- Signal two different vacuum levels to the original evacuation controller
* Rough vacuum reached
* High vacuum reached

- Diffusion pump temperature monitoring via three PT100 sensors
- Environmental temperature & humidity monitoring (external sensor)
### Device Overview
These are the main devices powering the succbone control system. For details,
please check the wiring diagrams in [`panel.pdf`](./panel.pdf).
- `-KEB1`: BeagleBone as main control system with addonboard for PSU & analog 0-10V readout
- `-KED1`: MikroTik RB450G router as gateway to the outside and network switch
- `-KED2`: MODBUS-TCP to MODBUS-RTU bridge
- `-KEC1`: MODBUS-RTU 8x relay output and 8x digital input board
- `-KEC2`: MODBUS-RTU 8x PT100 500°C transmitter
- `-BTA1`: MODBUS-RTU environmental temperature & humidity sensor
- `-QAA1`: Contactor for the roughing pump interlock
- `-QAA2`: Contactor for the diffusion pump interlock
