136188-01 Relay Output Extension Module

Thermistors are effective in detecting if the temperature limit of the motor windings is exceeded.PTC thermistors are usually mounted in contact with the motor windings and must be protected from overheating. When the rated temperature limit of the motor is reached, the resistance of the PTC increases.136188-01 When connected to the control unit, this signal can be used to automatically switch off the power to the motor. When selecting a PTC thermistor to protect the motor windings, manufacturers usually use three sensors in series, each located in one of the three stages of the motor. Any one of these sensors that rises in temperature to the trigger limit will energise any protection method designed to shut down the motor.

The type of winding sensor is not important as all the sensors mentioned will do the job. They will provide some kind of protection for the engine. There should always be the option of constant monitoring of your engine’s temperature because the 136188-01 will protect its windings, but it will probably stop your engine from producing what you want to stop. So, if you have the 136188-01 inside the motor, you can monitor the temperature of the motor, you can see if the temperature of the motor is higher than normal, and you can even set up an alarm that warns you when the temperature of the motor reaches a certain limit. So you will have some time to check what could be the cause of the temperature rise and try to eliminate it before it causes your production to stop.

Another thing is that the sensor temperature can fail at any time, so if you take continuous measurements of the temperature you will be able to see if the sensor is connecting or giving unrealistic values, such as a 30°C motor temperature when it is running at full load, or a 90°C motor temperature when it is not running at all. These unrealistic values will give you some indication that the sensor may be defective and perhaps you can modify the next planned stop for your process. However, with a PTC thermistor, the sensor could be damaged and the motor will continue to run until its windings are defective, then you lose your motor and your production stops
