1/4 DIN Temperature/Process Ramp/Soak Controller with Fuzzy Logic
SKU:
CN72000-Series
CN72000 Series 1/4 DIN Autotune Temperature/Process 16 Segment Ramp & Soak Controller with Fuzzy Logic includes a NEMA 4X Front Panel, isolated outputs and 24VDC power supply
The CN72000 Series temperature/ process controllers set a new quality, versatility, ease-of-use and value standards. Including many high-level standard features, additional function setup items appear in the control menu when a function is selected, simplifying the selection process. Units feature a universal input for thermocouple Types J, K, E, T, L, N, B, C, S and R, RTD’s, differential input (-10 to 10 mVdc); and process input (0 to 20 mAdc, 0 to 10 Vdc). A standard 24 V isolated, regulated power supply is included; operates most standard 4 to 20 mA transmitters. Standard features include autoune, fuzzy logic, fully adjustable PID, auto/manual control with smooth transfer and front panel activation key, percent output indicator, peak and valley indicator, loop break protection and indication. For process inputs, the display is fully programmable from -1999 to 9999 with selectable decimal point location. Most thermocouple and RTD inputs show whole or tenth degree displays. The CN72000 Series can be programmed for on/off, PID, heat/cool, or latching alarm. All outputs are isolated from the inputs. Outputs include 10 A relay, and scalable 0 to 20 mAdc.
