Description
Description
The CN78000 Series process controllers arefully programmable compact unitswith a variety of features thatinclude: universal input, self-tunePID, fuzzy logic and dual 4-digitLED displays for process and setpoint values. User can select fromthermocouple, RTD, current orvoltage inputs AC SSR, relay, DCpulse, and proportional currentoutputs. A programmable alarm(optional) can be reset automaticallyor manually. The front panel iswaterproof and corrosion-resistant(UL Type 4-X), making it ideal forsanitary applications. Electronicscan be replaced without wiringchanges through a removable frontpanel. Self-diagnostics, nonvolatilememory and selectable controlmodes are all also available andgreatly increase productivity. Foursecurity levels are passwordprotected. For optimal PID control,the on/off, P, PI or PID manual-tunecontrol functions can be selected,or the controller willautotune automatically.The CN78000 offers an excellentarray of standard features as well aspeak/valley indication, percentoutput indication, digital input filter,among others.

| E Thermocouple | -73 to 982°C (-100 to 1800°F) |
| N Thermocouple | -73 to 1300°C (-100 to 2372°F) |
| R Thermocouple | -17 to 1760°C (0 to 3200°F) |
| S Thermocouple | -17 to 1760°C (0 to 3200°F) |
| B Thermocouple | 24 to 1820°C (75 to 3308°F) |
| L(J DIN) Thermocouple | -73 to 871°C (-100 to 1600°F) |
| CThermocouple | -17 to 2320°C (0 to 4208°F) |
| Pt100 RTD (0.00385) | -200 to 875°C (-328 to 1607°F) |
| Pt100 RTD (0.00392) | -200 to 875°C (-328 to 1607°F) |
| RTD, 120 Ω Nickel (0.00628) | -80 to 320°C (-112 to 608°F) |
| RTD, Pt1000 (0.00385) | -200 to 875°C (-328 to 1607°F) |
| 0 to 20 mA*, 4 to 20 mA* | -1999 to 9999 |
| 0 to 10Vdc*, -10 to 10 Vdc*, -10 to 10 mVdc* | -1999 to 9999 |
Note: All thermocouple and RTD inputs can be set for 0.1° display. If temperaturegoes above 999.9° or below -199.9°, the display will return to whole-degree resolution.
* Process Input Types: The 0 to 20 mAdc, 4 to 20 mAdc, 0 to 10 Vdc, 2 to 10 Vdc,and -10 to 10 mVdc inputs are fully scalable from a minimum of 100 counts spanplaced anywhere within the range of -1999 to 9999. Decimal point position isadjustable from the zero place (9999), tenths (999.9), hundredths (99.99) orthousandths (9.999). |
