BCU 2001


The Brake Control Unit BCU 2001 records characteristic current and voltage variations, which are induced by movements of the armature disk in the magnetic field of the brake coil. In an interference free and reliable manner it evaluates the signal levels in terms of the control state (applied or released) and the maximum air gap (maximum wear).

Main Features:

  • EMC compatibility
  • Maximum air gap (wear) indication by LED
  • Maximum air gap indication by relay contact
  • Function on/off indication by LED
  • Function on/off indication by relay contact
  • No sensors on the brake
  • No sensor wiring to the brake
  • Perfect retrofit equipment
  • Directly connectable with PLC systems
  • AC and DC auxiliary power supplies applicable
  • Top-hat rail mounted


  • Container cranes
  • Ship winches
  • Automatic racking systems
  • Conveyor belts
  • General electrical drives


  • Combinable with the switching rectifier SGL in overexcitation mode
  • Combinable with bridge rectifier BGL-PE400/150/3
  • Combinable with half-wave rectifier EGL-PE400/150/3

Important requirements:

  • AC and DC circuit to be switched simultaneously
  • AC circuit may not be switched alone
