Ex heating control type FTSR-1 series 1130 / 1131

short description

are main part of an electrical heating control witch is typically installed in flame proof areas

is easy to use


    The heating control system consists of               1 Ex- Temperature - Controller                             1 Ex- power unit (with a main relay 25A)


Is used for the control the temperature of equipment in hazardous explosive ereas which require apparatus of category 2G / 2D Zone 1 / 21

Alle functions are implemented using a mechanical rotary encoder with push button function. With a short press the 7-segment display changes cyclically between the three types.

The power part consists of a single-phase high-performance relay output, the switching state is indicated by the green LED. It can switch nominal loads up to 25A.                            Load circuits with self-limiting heating cable and 20A rated current can be operated
