Hi Josh,
 
In synApps we support the Keithley 2700.  Each of those units takes 2 cards for a total of 40 thermocouples.  It costs about $2K, so $50 per thermocouple.  It can be extended with external multiplexors, but EPICS support would need to be written for those.

Controls experts,

  In the undulator hall of the LCLS we expect to monitor (what I
consider) a large number of temperature points (on the order of about
300). My past experience with thermocouples has been local installations
of between one and eight data points. It would be easy to just scale
that solution by a factor of 40, but I have to believe there are more
cost effective solutions.

  Can anyone with experience in this regard please point me in the right
direction? I'm looking for hardware that is, of course, EPICS compliant.

Thanks,
<josh>
