Description

Monitor and control temperature or process applications with precision using the CN7800 Series controllers. The CN7800 Series provides dual LED displays for local indication of process value and setpoint value. Control methods includes on/off, PID, auto-tune and manual-tune. PID control is supported with 64 ramp/soak control actions. Two additional alarm outputs are standard on the CN7800 Series. The alarm outputs can be quickly configured by using the 13 built-in alarm functions. The controller communicates easily with the built-in RS485 interface.

Rated 1 out of 5 by from Type "B" problem This controller has an issue with "B" thermocouple as the temperature range of it is 100-1,800C. Heating is not able to begin from room temperature such as 25C below 100C as it is out of range. This issue have to be fixed.

Rated 5 out of 5 by from Best Ramp-Soak controller for price I have three CN7833 controllers. They are not all that user friendly, but do a super job for the price. If I can't figure something out from the manual, Omega tech support has been quick to answer the phone and happy to help. I tried two other much less expensive controllers and had bad experiences with both. One made my kiln go run-away.
