Developped with layout and advantages of the New technology Platform (dual display, new microcontroller with increased operational capacity and data management), the unit ensures high levels of protection to electromagnetic interferences and ease of use which have made it the standard for this application.

The T154 maintains the standard 4 Pt100 inputs (3 phase transformer and a fourth option for the core or the ambient temperature), and 4 dry contact relay outputs, ALARM and TRIP, FAULT signal operation and start ventilation system (FAN).

On request, the unit is available with cULus certification for Canadian and American market, as well as RINA for marine applications.

All our units can also be supplied with a special coating on the electronic cards, resistant to difficult weather conditions, particularly characterized by high temperature and humidity (which are in tropical climates).

UNIVERSAL POWER SUPPLY: with input from 24 to 240 Vac-dc
