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 autoune, 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.

Selectable Inputs: Thermocouple, RTD, DC voltage, DC current, resistance (dependent on model)
Display: Two 4-digit, 7 segment, LED (red PV, green SV)
Resolution: 1.0, 0.1 (dependent on model)
Sample Rate: 8 per second
Accuracy: ±0.3% FS (thermocouple and RTD dedicated models), ±0.2% FS (universal input models)
Supply Voltage: 100 to 240 Vac (-15%, +10%); 50 to 60Hz or Optional 24 Vdc
Power Consumption: 3 W (thermocouple and RTD dedicated models), 6 W (universal input models)
Operating Temperature: -10 to 60‹C (14 to140‹F)
Humidity: 0 to 90 RH%
Control Output Ratings:
    Relay: SPDT, 30 Vdc/1A, 250 Vac/1A (18 and ¼ DIN models)
    Relay: SPST, 30 Vdc/1A, 250 Vac/1A (116 DIN models)
    Proportional Current (Isolated): 0 to 20 mA DC,
    DC Pulse: 12 Vdc/30 mA
Alarm Output Ratings:
    Relay: SPDT, 30 Vdc/1A, 250 Vac/1A
    DC Pulse: 12 Vdc/30 mA

Rated 3 out of 5 by from Cn418v-r1-r2 I have been using these temperature controllers for about 5 or 6 years now with about 15 in operation at an oyster hatchery. They are quite good for the price, but only seem to last about 4 yrs and then they get unreliable. I still use them and have only had one go bad in the 2 yr. Warranty period. Omega quickly replaced this unit.

Rated 5 out of 5 by from Easy installation, works well. This is a great temp controller, easy to set up and use. Works as it should. Not much else to say. I installed this on my wood furnace to control the intake damper, both protecting from potential overheat situations, as well as maintaining a minimum flue temperature to prevent creosote build up. Works great! Program the correct settings and this temp controller has essentially automated my wood furnace to self regulate.

I have a cn4316-r1-r2. In the settings I can select Output type (Opt) as ssR, will this unit actually work with a DC ssr or is setting redundant?

Asked by: Brad905
The model has two relay outputs which are what is physically in the Controller. The Opt parameter should be set for rELy only for the R1/R2 model and the SSR driver models would be DC1/DC2.

where can i find the physical dimensions?

Asked by: TBill
Thank you for your inquiry TBill. You can find the dimensions for each DIN size on the data sheet of this product on page 2. Here is the link:

What is the maximum current that these are rated for at 120VAC?

Asked by: joey
Thanks for connecting with Omega.The relay output is rated at 1A to 250VAC. Please contact us with any further questions.
