The temperature controller N1020 features advanced performance capability for the most complex and critical applications. Based on a high-end microprocessor and designed with a sophisticated auto-adaptive PID algorithm it continuously adjusts the PID parameters for best controlling The programmable input, configurable dual output along with the full range power supply provide maximum flexibility This 1/32 DIN size instrument has extremely small front dimensions of only 48x24 mm or 1/32nd DIN and is the right choice for controlling laboratory equipment when panel ■ High brightness red LED display • Programmable input: thermocouples, Ptl 00 RTD and 50 mV • Dual output: 1 pulse and 1 relay • Output funtions: control, alarm 1, alarm 2 ■ Measured value offset • Minimum and maximum limitsfor SPsetting • Minimum and maximum limitsforoutput value ■ Access password for configuration protection • Factory calibration settings restoration feature • Silicone keypad ■ Front pannel: IP65, polycarbonate UL94V-2 . AMBIENT CONDITIONS: Thermocouples, Ptl 00 and voltage (according toTabel 01) Internal Resolution: 32767 levels (15 bits) Display Resolution: 12000 levels (from -1999 to 9999) Input sampling rate: up to 55 per second Accuracy: thermocouples J, K,T, E: 0.25 % of span ±1 °C Accuracy: thermocouples N, R, S, B: 0.25 % of span ±3 °C Input impedance: Ptl00 and thermocouples: > 10 MOhm Ptl00 measurement: 3-wires, (=0.00385) with cable length compensation, 0.170 mA excitation current . OUT1: voltage pulse; 5 V / 25 mA / (Zout= 47 Ohms) . CONNECTORS PROTECTION: IP30, ABS+PC UL94 V-0 • Programmable PWM cycle from 0.5 up to 100 seconds ■ Operation starts 3 seconds after power up ACCEPTED SENSORS AND MAXIMUM RANGES TIMER FUNCTION A built-in timer function is available for time down monitoring during control cycles. The timer start/stop options are: • When PV value reaches control SP value; . When starting control (RUN= YES); • Through the "F" key - reset mode: by pressing "F"the timer is automatically zeroed and a new cycle is started; . Through the "F" key - ON/OFF mode: by pressing "F" the timer halts; by pressing "F" again the timer resumes counting. Options for Time Down function: • At the end of the time cycle control output (RUN= NO) goes off; • At the end of the time cycle the alarm output goes off.
