Design of a vacuum chamber interlock box for the EELS experiment.

We fear electric power outages!

Control inputs: 
1) Pressure transducers (Ion gauge and convectron gauges). 
2) Water flow meter (acts as a variable resistance, we fear outages). 

Control outputs: 
1) Solid state relay for diffusion pump power 
2) Solid state relay for (other?) power
