The CN8500 temperature controller is extremely versatile and user-friendly. The operator needs to review only those parameters relevant to the particular application during setup. A dual digital display offers optimum process information at a glance. The dedicated upper display shows the process temperature, while the lower display displays setpoint and setup parameters. Individual LED’s identify the status of outputs, alarms, digital communications and special options. The CN8500 features a NEMA-4X front panel and a universal power supply that accepts 103 to 253 Vac and 103 to 330 V dc. Control algorithms available are P, PI, PD, PID, or ON/OFF. The autotune feature automatically sets proportional band, rate and reset before the process reaches setpoint. These parameters provide quick stabilization of both the heating and cooling process without overshoot, hunting or cycling. The standard dual control outputs can be configured in a variety of control and alarm applications such as heat, heat/cool, heat/alarm, cool, or cool/alarm. The Ramp to Setpoint feature allows the user to define the rate of rise to reach the setpoint, thus minimizing thermal shock to the load during start-up.
