Digital temperature relay TP-100M is a microprocessor device designed to measure and control the temperature of dry-type transformers.
The device can also be used for the protection of motors and generators.

• Temperature mode control over four channels.
• Temperature display on the device.
• Sounds an alarm in emergency situations.
• Load control for cooling of the transformer.

The device can be used with the following types of temperature sensors:

• PT100 – platinum sensor with a nominal resistance of 100 Ohm, at 0 °C;
• PT1000 – platinum sensor with a nominal resistance of 1000 Ohm, at 0 °C;
• РТС1000 (EKS111) – sensor with a nominal resistance of 990 Ohms, at 25 °C;
• PTC (minika) – cold resistance of the sensor 20-250 Ohms.
