The digital timer — the thermosta
INFORMATION ON THE PROJECTInstallation of time 0,5 … 99 hours Installation of temperature 10 … 80 ºС Threshold of restriction of temperature 80 ºС Accuracy of maintenance of temperature ±1 ºС Exit of power supply of additional devices of 3 V, 20 ma
The controller is intended for application in devices where management of temperature during the set time, for example drying cabinets, etc. is required.
Has 2 dependent control paths loadings — the heater and the fan.
Has 2 digital sensors of temperature:
- for control of temperature of an object;
- for control of a heating element and protection against an overheat.
The adjusted PID-algorithm allowing to maintain temperature with high precision is applied to exercise control and indication of serviceability of sensors. Non-volatile memory of settings provides resumption of work after loss of tension in network. Wide range of tension of a power line: 100 … 260 century. It is executed in the form of the printed circuit board with elements, own power supply unit, two LED indicators and buttons. Power components (simistor) are mounted out of a payment on the heat sink. Management of simistor has a galvanic outcome. There is a low-power exit for power supply of additional devices.
