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.
SPECIFICATIONS 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 (1⁄8 and ¼ DIN models) Relay: SPST, 30 Vdc/1A, 250 Vac/1A (1⁄16 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

Cn418v-r1-r2I 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.

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.
