ROPE - BG90-101 Braking device assembly - Functional description
The BG90 replaces the brake contactors required by EN81, as well as an electronic brake control for overexcitation of the brake coils.
of the brake coils. The BG90 can be used to control brake solenoids for elevator drives with rated currents of up to 2.5A.
This means that no brake contactors or additional electronic brake control are required when using the BG90.

adjustable time (0.5..3 seconds) from 200VDC to 50..150V (adjustable).
To control the brake coil, the two enable inputs must be supplied with 230VAC from the safety circuit.
The mains voltage (230VAC)= is always present. If the safety circuit is interrupted and therefore the enable inputs cannot receive any
control voltage, the brake coil is safely disconnected from the mains voltage. This is achieved by an
intrinsically safe electronic circuit (functional safety) without additional contactors.
