CN1507TC is a CN1507 series process controller. This compact unit offers the features of up to 7 controllers in a single 1⁄8 DIN enclosure. Careful design, high functionality and compactness allow it to offer the best cost/performance ratio of any controller in its class. The input type for each zone is selected independently. Scaling and offset allow current and voltage signals to be converted and displayed in engineering units. Temperature can be displayed in Centigrade or Fahrenheit. Additionally, each zone has its own ramp/soak profile with up to 7 segments. On/off, as well as PID control, is offered for optimum process stability. Processes that do not require tight control through complex tuning of PID parameters can be run under simple on/off control. Each zone has its own set of on/off and PID parameters and each zone can be programmed for heating or cooling.
