Simulation of RTDs and Thermocouples

[Bennet Williams]

I'm facing a serious challenge of how to simulate some RTDs and
thermocouples for an automatic (PLC-controlled) hardware simulation
system that I am proposing. I'm not really looking for "outrageous"
ideas like a servo motor turning a pot, etc. I would prefer to use
off-the-shelf units, but a discrete component circuit would be OK, if
necessary.

I tried googling for something, but only came up with human-adjustable
simulators. I need something that can be controlled by a PLC. In
defeat, I turn to you - please help!

Sorry I missed the bit about needing PLC control. Best I could dind is one
with an RS232 port.

Thanks for the link. I can use this one. I will be capable of
interfacing via RS-485 or IEEE-488.
