I'm working on a project were I will be using Heating Plug Element- http://www.omega.com/ppt/pptsc.asp?ref=CSS_CSH&Nav=head01 I want to be able to control temperatures up to 1000 F using something likes this: http://www.omega.com/Manuals/manualpdf/M4636.pdf I would like to be able to control the temperature of the plug heaters so that I am able to set a maximum temperature, which is held for a period of time before shutoff. Nothing overly elaborate. There will be no other electrical components, just the plug heater and the thermostat controller. I'm not clear on how controllers of this type work. The output for the controllers is either DC Pulse, Relay, or 4-20mA (is up to the buyer). For my described application which output would be the simplest? What additional hardware would I need for what is suggested? Thanks!
