## **Specifications** 

## U **Autotune** 

**Selectable Inputs:** Thermocouple, RTD, DC voltage, DC current, resistance (dependent on model) 

- U **Dual 4-Digit LED Display and Indicators for Output and Alarm Status** 

**Display:** Two 4-digit, 7 segment, LED (red PV, green SV) **Resolution:** 1.0, 0.1 (dependent on model) 

- U **Single Alarm Output** 

- U **Universal Power Supply** 

**Sample Rate:** 8 per second 

**Accuracy:** ±0.3% FS (thermocouple and RTD dedicated models), ±0.2% FS (universal input models) 

## U **Isolated Analog Control Output (Selected Models)** U **10 Segments of Ramp/Soak (Selected Models)** 

**Supply Voltage:** 100 to 240 Vac (-15%, +10%); 50 to 60 Hz or optional 24 Vdc 

**Power Consumption:** 3 W (thermocouple and RTD dedicated models), 6 W (universal input models) 

The CN4000 Series temperature/process controllers set a new standard for ease-of-use and value. Units feature dedicated input models with thermocouple and RTD inputs, and models with universal inputs for both temperature and process inputs. Standard features include autotune, fuzzy logic, fully adjustable PID or on/off single control output with one alarm. Selected thermocouple and RTD input models can show whole or tenth of degree display resolution. Output types include relay, dc pulse, or an isolated analog 0 to 20 mA output.
