The CN1500 series is a compact unit that offers the features of up to seven 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.
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. Setpoint deviation, positive as well as negative, can be viewed.
Additional functions include min/max reading for each zone, indefinite program hold, automatic scanning and displaying of different zones and three display modes (setpoint only, process only or both setpoint and process). Power, control, and process signal connections are conveniently made with Euro-style plug-in connectors.
Each zone has a three-digit long engineering label that can be programmed to indicate the type of process being controlled, e.g., °C or °F for temperature, PSI for pressure, etc. Every controller’s output status is indicated by LED’s. Channel-to-channel scan time is also programmable.
