Ex heating controller type FRBL-2 series 1064

short description

the comprehensive solution for controlling and limiting the temperature                                    incl. power control unit consists of a main relay, full wave control and phase angle control

FRBL-1-geschlossen-10-hoch0302

    The heating control system consists of               1 Ex- Temperature-Limiter                                    1 Ex- Temperature - Controller                             1 Ex- power unit (Triac)

Function

The Ex heating controll type FRBL-2, series 1064 in conjunction with a PTC resistance thermometer is used for the control , limitation and “energy controller” of the temperature of equipment in hazardous explosive ereas which require apparatus of category 2G /2D Zone 1 / 21

FRBL-2 series 1064 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.

Features

  • The FRBL-2 contains the controller, limiter  and the 5% step switch “energy controller”
  • to the power supply because of full wave or a continuous control with SSR (solid-state relay)
  • overload circuit at >25A
  • Attitude of the temperature levels in the category 2 permits
  • connectiont to resistance temperature sensor   Pt100 DIN in 3- or 2-wire configuration                  
  • Signalling of sensor break and sensor      short-circuit signal
  • Greener-LEED-indication of the main contactor´s switching position
  • adjustment of switchpoint with tool only (screwdriver)
  • temperature sensor shortage or breakage shown by 7-segment LED display for controller and limiter
  • unlock at device or remote
  • no unlock necessary after breakdown of power supply
  • optional : Ex- amperemeter, attachable
