Digital temperature relay TR-100

It can be used to protect:
•  engines and generators;
•  three-phase air transformers with additional core or environment temperature control.

TR-100 can use any voltage between 24 and 225V, regardless of the polarity.

The following thermal sensors can be used by TR-100:
•  PT100 – platinum sensor with nominal resistance of 100 Ohm at 0 °С;
•  PT1000 – platinum sensor with nominal resistance of 1000 Ohm at 0 °С;
•  KTY83 – silicon sensor with nominal resistance of 1000 Ohm at 25 °С;
•  KTY84 – silicon sensor with nominal resistance of 1000 Ohm at 100 °С;
•  PTC (1, 3, 6 serial connection), cold resistance of 20-250 Ohm.
