The Si24DiTEPTC1-12B-50V-20A is a 50V 20A, microprocessor based, closed-loop, Digital, Thermo-Electric, Proportional Temperature Controller board that heats or cools a thermal-zone. The temperature is measured with a 12-bit digital sensor and proportionally controlled with 0.0625C steps in the -25C to +102C range. An efficient high-power H-bridge controls the current (in the 0 to +/-20A range) to Peltier type Thermo-Electric (TE) cells, functioning as a bidirectional heat-pump. By proportional control, we mean that the amount of correction used in the closed-loop is proportional to the difference between the set and measured temperature values. Two user selectable proportional control grids G8 or G9 are used to control a wide range of thermal loads. Grid G8 is used for small loads (selected when J1 is installed) and G9 is used for large loads (selected when J1 is open). An onboard microprocessor measures and controls the temperature; monitors the user inputs; and drives a 2 line x 20 character LCD. A small 12-bit digital thermometer is used to measure and control the temperature in the -25C to +102C range, with ½C accuracy. As the name digital (Di) implies the desired set-temperature is adjusted with the Si24PB2-MC3 Up and Down push-buttons in 0.06250 C steps. An LCD port (with HITACHI HD44780 Interface Standard) is provided for display of the Set and Measured temperature data.
