TDE-0301 temperature controllerA .Technical specification:1、Input:  K     Measurement precision: ≤1.5%FS±1B2、Measure and control range: 0~399℃3、Control period: 30±10Sec;  Proportional band range:2～6%4、Deviation display range: -50～50℃5、Output contact capacity: AC220V 5A（resistance load）6、Power voltage: AC110～220V  50Hz/60Hz7、Working environment: Temperature: 0~50℃;relative humidity: ＜ 85%RH,Website: , without corrode gas.8、Overall size and installation hole（mm）： 48×96×110、 44×92；B. Connection Scheme(consult):C. Method to use:Connect the power and the sensor according to the connection scheme, then it displays the actual measured temperature.The terminals of '1’, '2’ are input of thermocouple signal, the terminals of '6’, '7’, '8’ are relay control output. When the green light of "OUT" brighten, terminal '7’ and '8’ are connected and terminal '6’ and '8’ are disconnected. When the green light of "OUT" goes out, terminal '7’ and '8’ are disconnected and terminal '6’ and '8’ are connected. The terminal of '3’, '5’ are power supply (AC110～240V). When the actual measured temperature don’t enter the proportional band and the setting temperature is higher than the actual measured temperature, the terminal '7’and '8’connect, terminal '8’ and '6’ disconnect. The load starts heating at this time and its temperature is going up. When the actual measured temperature don’t enter the proportional band and the setting temperature is lower than the actual measured temperature, the terminal '7’ and '8’ disconnect, terminal '8’ and '6’ connect. The load does not heat at this time and its temperature is going down. After the actual measured temperature entry into the proportional band, the relay start opening and closing according to the controlling rule. The higher temperature, the shorter connecting time of relay between terminal '7’ and '8’. Vice versa .The controller controls the temperature by the way of changing the average heating power of load.Note: Time proportion adjustment: the time proportion is also known as intermittent ratio adjustment, change the average heating power to achieve control in the unit time (cycle). When the actual temperature access to the dashboard proportional band, relay release cyclically, suction, by changing the absorption and release time proportion to change the average heating power of heat load, thus changing temperature for purpose.Note: Our company will continue to improve product technology, design specification.
