Heating Element Protection Integrated Circuit Modules
A heating element converts electricity into heat, of course, must use a safety circuit, so At high temperatures do not occur.
besides that, in order to protect the heating elements and other devices.
A secondary back-up protection will include monitoring temperature heating elements. Heating Element Integrated Circuit Protection Modules using LM741, Thermistor will work as excessive heat. If excessive heat will then move the thermistor relay and eventually cut off the electricity to the heating element, the Relay will protect from damage caused by equipment that is too hot. Relay is in use because of the size of a large electric 30mA. And standard redundant relay protection is provided by using a heating element Type W to 500W.
