The CN4400 is an economical 1/16 DIN process controller that accepts temperature or process inputs. It has sophisticated control capabilities, providing PID, autotune PID and on-off control. The CN4400 is available with mechanical relay, SSR driver or 4 to 20 mA output. For fast hook-up, the CN4400 features a removable socket mount design with screw terminals. The ramp to setpoint function allows control of the rate of ascent/descent each time the setpoint is changed. The CN4410 offers four segment programming, ramp to setpoint one, soak for a specified period, ramp to setpoint two, soak at setpoint two, and either start over or shut the process down.
