Hi Terry,

No, it's pretty easy. A PLC might be a perfect choice for a long running 
test bed. I use a PLC for my deadman switch, VFD status for the 
sparkgap, etc.. The PLC will react to inputs you state in the logic 
program. The programming is super simple and you can control disconnects 
or whatever in the event of any situation. Software is free.

If your interested in a small 3" x 2" computer (PLC), just contact me 
off list. No charge. It's good for at least 5 years of running. It runs 
on 24 VDC and even has PWM output capability on 2 outputs (including PID 
control). The software is free and like I said, super simple to program.

PLC's can do almost anything. Much depends on the programmer, the task, 
and the number of I/O's. The PLC I have for you if wanted is perfect for 
a test bed controller. You can program a contactor disengagement for any 
situation you deem as "time to shut down". It has 24 inputs and 16 
outputs (more than enough for most projects). Just let me know if your 
interested.

Take care,
Bart
