[labnetwork] Interlock Boxes

[Hathaway, Malcolm]

Hey All,

I seem to have hit the wrong reply button on Thursday, but here's the scoop at Harvard...  (sorry that some if this will seem dated now...)

Hi Kolin,

What we are using in our CLEAN system at Harvard is a "semi-custom" ICP box (Interlock Control Panel), which uses a 6-channel ethernet connected relay called an ADAM (p/n ADAM-6060-BE) from Advantech.  These are built into the ICPs, which are put together by our lab consultant Jim Loach (cc'd), who also does most of the in-lab wiring.  I'm sure he'll be delighted to make some of these for you, and perhaps even go to your facility to do installations.

The ICPs provide 6 sets of dry contacts or 12V outputs which are then tied to either 12V relays which control equipment (most typically PC video monitor) power, or, in the case of dry contacts, they are tied in series with existing system interlock switches (panel interlocks, gas box door interlocks, water-flow interlocks).  In this way, the tool in question is disabled, either due to a blank control monitor, no system power, or an on-board interlock.  The trick is to find ways to disable a system that don't break the tool if they kick in during a process...

We have found it helpful to mechanically secure the monitor and equipment power cord plugs to their respective equipment, to prevent the occasional cheater from removing the relay-driven power cord and installing a standard modular cord in its place.

We use ethernet relay boards from National Control Devices<http://www.controlanything.com/Relay/Relay/ETHERNET_PROXR>, controlled by Badger (the new version of Coral). NCD also makes wifi connected relays. Having two relays on a board makes it easy to keep isolated grounds isolated. Each board requires its own static IPv4 address. The boards can be easily mounted in a 6"x6" electrical box, or in the custom-fitted plastic case from Badgerlms.<http://badgerlms.com/> I suggest you keep these boards behind a firewall, since they run a tiny operating system and web page, but with only minimal security.

Hi All,

EPFL is using Ether IO24 R from http://www.elexol.com/IO_Modules/

Our software is homemade but we have a call for tenders running in order to “couple our homemade software” with a commercial package.

We will keep you posted on this important move on which we are investing a lot of effort.

With my very best regards,
Philippe

Kolin:

I believe that most folks are using the Advantech ADAM-6060 or ADAM-6066 6-channel IP-addressable relay modules for interlocking.  Others use modules that come from National Control Devices that have 1-, 2-, 4-, and 8-relay devices with current ratings from 5 to 30 amps.  Most folks are currently using hard-wired ethernet connections, but some wireless options are also available.

I believe that most of these IP-addressable relays are functionally equivalent but would certainly have minor differences in the default port that is used and the exact command sent to turn on, turn off, or check the status of a given relay channel.

I don't have experience with either Cores or iLab software to know what, if any, interlocking hardware has been interfaced with their systems.

Good luck,

John

Hi!  Here at WVU, we are going to interlock our tools to our reservation software.  Everyone at the UGIM was talking about the “blue boxes” from Advantech.  Can anyone provide me with a model number?  Also, has anyone interfaced these boxes with Cores or iLabs software?
