PURPOSE OF THE RELAY
 Thermistor relay RT-M01-1-15 is designed to protect the motors from overheating during prolonged start or stop, undervoltages, overvoltages or over-switching frequency, contamination of channels of cooling coils, etc. The relay is connected to thermoresistive sensors (PTC) built-in the motor winding.
 
 
DESIGN OF THE RELAY
 Relay is produced in a plastic case with a unified front connection wires power and switched circuits. Mounting is carried out on a DIN rail  width 35mm (GOST R IEC 60715-2003) or on a smooth surface. To set on a smooth surface, you need to push locks. Terminal design provides robust clamp wires up to 2,5mm2. On the front panel there are: green indicator of power on "U", yellow indicator of actuation built-in executive relay "", red indicators "Short circuit of sensors" and "Overheating" for visual analysis alarm modes of the engine.
 
OPERATION OF THE RELAY
 The relay controls alarm modes of engines, that are manned by built in temperature sensors, which are used as a PTC thermistor (PTC resistors).
 The relay functions independently of rated motor current, the class of insulating materials and the type of start-up. Successively included sensors connected to terminals "T1" and "T2". The number of connected sensors is limited by the total resistance of separate PTC R=R1+R2...+ Rn <= 1,5 k.
 In normal engine mode the resistance of the sensors does not reach the threshold of actuation, and the built-in executive relay is turned on and the contacts 21-24 are closed. When heated even one sensor and the excess value Rload the relay is tirned off and contacts 21-24 are opened, contacts 11-12 are closed.
 After cooling of sensors and achievements the value Rcooling the relay automatically turns on, closing contacts 21-24.
 Upon detection a short circuit in the sensors circuit (Rshort circuit <25Om) - relay turns off. As sensors of temperature protection can be used posistors type CT14.2. Properties of the relay allow to use other posistor temperature sensors conforming the requirements of DIN44081 and DIN44082.
 Thermistor relay combined with PTC thermistors can also be used for temperature control: ventilators of hot air; bearings; oils; air; heating systems; transformers.
