Ex heating controller type FRB-1 series 1087

short description

the comprehensive solution for controlling and limiting the temperature incl. power function

FRBL-1-geschlossen-10-hoch03

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

Function

The Ex heating controll type FRBL-1, series 1087 in conjunction with a PTC resistance thermometer is used for the control , limitation and electric contact of the temperature of equipment in hazardous explosive ereas which require apparatus of category 2G/2D  Zone 1 / 21

FRBL-1 series 1087 are main part of an electrical heating control in the flame proof areas are installed and intrinsically safe electric circuit for the sensors has. Measured value processing via micro controller.
