[labnetwork] Commercial power interlocks compatible with NEMO

[Hathaway, Malcolm R]

Hi Shane,

I don't know if the ones we use are NEMO-compatible right out of the box, but the CLEAN system at Harvard CNS uses ADAM-6060 6-channel relays from Advantech.  They are the only such ones I've run across, so perhaps everybody uses them, if they don't make their own.

Just needs a static IP address, and compatible control software (which I suspect is quite generic)...  Only drawback is they only have 6 channels, so you need many of them scattered around the labs to serve everything that is interlocked.

We have them in these little boxes, which can serve up 6 sets of "dry contacts" (to work in series with tool internal interlock circuits), or 12V outputs, which we use to trigger power relays for equipment control PC monitors.

Dear Shane,

Here at the LSU cleanroom we use NEMO and implemented an IP interlock
system with a Raspberry PI an Arduino UNO and a 24V relay driver
shield plus some Python code written by a CS student. We are happy
with the results. If you are interested in learning more I am happy to
discuss.

Regards,
Kevin

Hi Colleagues,

I saw that NEMO had been discussed here before. We are interested in NEMO as well.

What's challenging for us to figure out is identifying IP-based power interlocks. I think that a lot of you bought FPGA boards and progammed them yourselves. Are there any commercial products compatible with NEMO and are ready to use with no or minimum customisation.

Cheers

Shane
