-way temperature controller can set as "refrigerating" or "heating", using 10K general NTC thermistor to control temperature, control -way relay (NO, NC) outputIt is widely used in various refrigerating and heating situations.Under refrigerating mode, the output opens when the temperature is above (temperature control value + return difference) and stops when temperature is at the temperature control valueUnder heating mode, the output opens when the temperature is below (temperature control value - return difference) and stops when temperature is at the temperature control value.Adjustable temperature control value and return difference value with correction function for measured temperature deviationAdopt DIN guide rail type installation, easy and fast to installAdopt the advanced design of isolating supply, ensuring the controller work steadily, reliably and continuously when the supply changes between 100V~250V ADC.One-way 10K NTC temperature sensor input and one-way NO & NC outputShifting between the refrigerating and heating modes with temperature displayDelay protection of compressor and -down memory protection functionThe temperature sensing line could be connected with general wire for 100 metersSet the parameter to conserve long-term memory of -down.NOTE: The max load current of this product is 10A, please an allowance (around 6A) during long-term using to increase the using time. The parameters and set in the user manual are those when the load connects onto the NO end. If connection onto the NC end is required, please set accordingly.Color: As shownMaterial: Metal + PCProbe Model: Water Drop ProbeInstallation Mode: Standard DIN rail installation or fixed installationDisplay: 22 * 11mm 3 Digits LED Display Supply: ADC 110-240V: 2WButtons: Press-type Membrane KeypadInput: One-way (10K)NTC thermistor temperature sensor output, measuring range of -50 Celsius ~120 CelsiusOutput: 1. One-way relay NO Touch-spot is for refrigerating output and NC Touch-spot is for heating output.2. The current capacity of the output Touch-spot is 5A of restrictive load and 1A of inductive load. It can control the 1000W electrical heating or electrical motor or water pump of 200W. AC contactor is needed to enlarge the capacity for greater load.Working Temperature: -10 Celsius~50 CelsiusMeasuring Range: -50 Celsius~120 Celsius Setting Range: Minimum Limit: -45 Celsius~controlled temperature, Maximum limit: controlled temperature~110 CelsiusTemperature Control Return Difference: 1~30 CelsiusDelay Time: 0~300SDeviation Correction: -25~25CelsiusItem Size: 93 * 55 * 44mm / 366 * 217 * 173 inchItem Weight: 84g / 296ozPackage List: 1 * Temperature Controller1 * NTC(10K) Temperature Sensing Line 1 * User ManualOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
