Digital temperature controller Orion Italia

The Temperature Relay TR-42 has been designed for continuous monitoring of the temperature, the cooling fan's control and overheat protection for resin or air insulated three-phase transformers.

Thermal detectors PT100 DIN 43760, three of them located inside the transformer coils and the fourth at the core, detect the temperature.

The TR-42 relay is microprocessor-based equipment designed to satisfy all control requirements and guarantee high reliability.

The TR-42 perform the following functions:

Measurement:

* Coils and core transformer temperatures, automatically each 5 sec or manually.
* Highest temperature indication and storage.

Signaling and programming:

* 7 segment display and led indication.
* Simplified programming through frontal push buttons.
* Display and non volatile storage of: alarm temperature, trip temperature, fan on, start and stop fan temperature, highest RTD temperature, baud rate of serial transmission, and assigned relay address.
