Description

Electronic microcontroller based on temperature control of dry type MF and cast resin transformers.

Developed with the layout and advantages of a new technology platform (dual display, new microcontroller with increased operational capability and data management), the unit ensures high levels of protection for electromagnetic interference and ease of use that has made it the standard for this application.

The T154 maintains standard 4-bit 100 inputs (3 phase converter and fourth option for core or ambient temperature), and 4 dry contact relay outputs, alarm and trip, fault signal operation and start of ventilation system (fan).

The T154 temperature relay provides a high level of protection against electromagnetic interference and ease of use making it a reference for this application. Provides 3-phase transformer temperature control and a fourth option for central or ambient temperature.

The back terminals are removable.
It has 3 or 4 100 bit RDT input, input channels are protected against electromagnetic noise and overvoltage.
Two output relays (Alarm triggered): Output relay for fan control (FAN) and 1 relay for sensor failure or operating abnormality (FAIL)
Self-extinguishing condition in ABS Norel 94FU
Polycarbonate plate IP65
Data storage: 10 years minimum
Universal power supply with 24 to 240 V DC input.
