Just some guy from
inexpensive, works well.
I use this controller to maintain the temp in a molten salt furnace. With the auto tune it holds a constant temp with minimal over shoot and fast reaction time.

Reliability is marginal
Originally had six units, three failed after 1 year. The internal relay contacts became intermittent, one fused in the "on" position. They are only switching 2 amps, and are rated for 5.

CN9000A Replacement
Perfect replacement to the CN9000A, to be used in a NASCAR Oil Temperature Heater control for warming the engine oil and circulation before the engine is started. With this ability we don't have keep as close as an eye on the oil temperature in the tank while working this process that takes approximately 1 hour.

1/16 DIN Temperature Controllers
Product works well and can easily be integrated with most controls systems. The only complaint is that the lead time is often quite long if the items are not in stock.

Controller features have On/Off and PID Control
Because this controller has both On/Off & PID Control I was able to configure it to my oven.
