OMEGA Engineering, Inc. Autotune PID/On-Off Controllers CN9000A

The CN9000A digital temperature controllers feature high accuracy and reliability, and the sophisticated PID with approach control for optimal control during start-up and steady-state operation. These units are well suited for a broad range of applications, and are easy to install and operate. The unique, sophisticated autotune algorithm will calculate the optimum PID values, and additionally recommends the best value for cycle time. For most applications, the user need only select the desired input type, simply by using the front pushbuttons. The autotune parameters can be changed by the operator at any time, allowing the operator to fine tune the controller to an individual process. The microprocessor holds all data in non-volatile memory, with the ability to retain data for 10 years with no power. The CN9000A has a large, 3 1/2 digit green LED readout, with auxiliary indicators for each output, and 3 LED’s to indicate deviation from setpoint.
